Geography Grade 11. Use this case. A July chart over Cape Town. A low sits south-west of the Cape. Winds circle it clockwise. The cold front is the line with triangles. Ahead of it, north-westerly cloud and rain. Behind it, cooler air and showers. The Namib, under sinking air near 30 degrees south, stays dry on the same day. One chart, two parts of the same cells: rising air and a front at the Cape, sinking air on the desert coast. In sentences, say what The atmosphere is doing here, from the situation to the result.

1. What is the question asking?
Read the question twice. Circle the unknown. Underline every number and unit. The paper is asking: Geography Grade 11. Use this case. A July chart over Cape Town. A low sits south-west of the Cape. Winds circle it clockwise. The cold front is the line with triangles. Ahead of it, north-westerly cloud and rain. Behind it, cooler air and showers.

In sentences, say what The atmosphere is doing here, from the situation to the result.
In other words — as if you have never seen this before
The atmosphere. Warm air rises at the equator, travels poleward high up, sinks around 30 degrees, and returns as trade winds. That is the Hadley cell. Similar cells sit in the mid-latitudes and at the poles. Where air rises, rain is common. Where it sinks, deserts are common. The spinning Earth bends the winds. A synoptic chart draws the result for one day: highs, lows, and the fronts between warm and cold air. In the southern hemisphere, air circles clockwise into a low.
2. What do we already know?
The dry Namib and a Cape winter front are the two African cases of this one atmosphere.
3. Which method — and why this one?
The atmosphere. Warm air rises at the equator, travels poleward high up, sinks around 30 degrees, and returns as trade winds. That is the Hadley cell. Similar cells sit in the mid-latitudes and at the poles. Where air rises, rain is common. Where it sinks, deserts are common. The spinning Earth bends the winds. A synoptic chart draws the result for one day: highs, lows, and the fronts between warm and cold air. In the southern hemisphere, air circles clockwise into a low.
4. Step-by-step working
01 / 07
What it is
The global atmosphere moves as cells of rising and sinking air, and those cells make the winds and the rain belts.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.

How it works

03 / 07
Worked theory
Worked theory. The Namib and the equator. Air rises over the hot Congo basin and rain is heavy. The same air sinks over the west coast of southern Africa, so the Namib stays dry even though the sea is next door. Sinking air does not favour rain. On a winter synoptic chart, a low and its cold front cross the Cape. Ahead of the front the wind and the cloud change. Behind it the air is cooler. The chart is the cells and the fronts, drawn for Wednesday, not a new kind of atmosphere.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
04 / 07
Say it back
Rising air brings rain. Sinking air brings deserts. The Hadley cell links the equator to the 30-degree deserts. Southern-hemisphere lows spin clockwise.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
05 / 07
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
06 / 07
Step F — Box the answer with its unit
Rising air brings rain. Sinking air brings deserts. The Hadley cell links the equator to the 30-degree deserts. Southern-hemisphere lows spin clockwise.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
07 / 07
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.
5. The answer
Rising air brings rain. Sinking air brings deserts. The Hadley cell links the equator to the 30-degree deserts. Southern-hemisphere lows spin clockwise.
Copy onto your answer sheet — in this order
Answer: Rising air brings rain. Sinking air brings deserts. The Hadley cell links the equator to the 30-degree deserts. Southern-hemisphere lows spin clockwise.
6. Check it like a marker
The answer names the situation, what changed, and the result. It does not stop at a heading.
7. A trap first-timers fall into
A common mix-up is to spin southern lows anticlockwise, the northern-hemisphere way, or to expect rain wherever there is a coast.
2 · 4 Marks · Geomorphology
Geography Grade 11. Use this case. Waterfall, then meander. High on a Drakensberg stream the gradient is steep, the valley is narrow, and the water falls over a hard band. Far downstream the gradient is gentle, the river bends, and a meander can be cut off as an oxbow. The river did not “get tired”. The slope changed, so the work changed, from cutting down to swinging sideways. A label that says the waterfall is in the lower course has the profile backwards. In sentences, say what Geomorphology is doing here, from the situation to the result.

In other words — as if you have never seen this before
Geomorphology. Weathering breaks rock in place. Erosion carries the pieces away. Mass movement is the slide or creep of soil down a slope under gravity. A mesa is a flat-topped hill with a resistant cap. A butte is the smaller remnant. A canyon is a river cut deep. Hard rock stands out. Soft rock wears away. Slope shape tells you whether the slope is retreating or wearing down.

Worked theory
Worked theory. The Valley of Desolation near Graaff-Reinet, or any dolerite-capped hill in the Karoo. The dark cap resists weathering. The softer rock beneath wears back. The cap is left standing as a mesa, then a butte. A river in flood does the carrying. A rock that cracks from heat and cold has only been weathered until water or gravity moves the pieces. Calling every hill a volcano misses the cap-rock story, which needs no eruption.

04 / 07
Say it back
Weathering breaks rock in place. Erosion moves it. Mesas and buttes are resistant caps left behind. Slope shape is a process, not a label.

Geography Grade 11. Use this case. Two municipalities, one GDP. National GDP per person can rise because mining profits are counted in Johannesburg, while a rural municipality in the same year still has a clinic an hour away and a school without a library.

In other words — as if you have never seen this before
Development geography. Income per person is one indicator. The Human Development Index adds health and schooling. A country can be rich in minerals and still unequal. Developed and developing are rough labels for that mix of income, health and education. The core-and-periphery idea says investment and skilled work gather in a few places, while other places supply labour and raw materials. Development is a pattern, not a prize given to a continent.

Worked theory
Worked theory. Two South African places. Sandton has offices, clinics and schools close together. A former homeland town may have a lower income, a longer trip to a hospital, and many people sending wages home. The national GDP looks healthier than the town feels, because GDP averages the Sandtons with the towns. HDI moves when a clinic and a school arrive, even if no new mine opens. Calling the whole of Africa “undeveloped” erases the Sandtons and the cities that function. The indicator you chose changes the sentence you are allowed to say.

Say it back
Development is income plus health plus education. GDP alone hides inequality. Core regions concentrate wealth. Peripheries supply them.

4 · 4 Marks · Resources and sustainability
Geography Grade 11. Use this case. A borehole pumped dry. A borehole is renewable only if pumping stays below the recharge. A farmer runs the pump all day in October. By December the water level has fallen and a neighbour’s shallower hole fails. The rain that should have refilled the aquifer was less than the pump removed. More pumping is not the cure. A slower pump, or a crop that needs less, is. Coal does not refill on this clock at all. Groundwater can, and this farmer spent it faster than the refill.

Resources and sustainability. Renewable resources, such as sunlight, wind and, if managed, forests and fisheries, refill. Non-renewable resources, such as coal and oil, do not refill on a human timescale. Soil is renewable only if erosion is slower than soil formation. Overstocking, ploughing down the slope and cutting all the trees make soil a wasting resource. Sustainability means using a resource so that people next decade still have it.

Worked theory
Worked theory. A hillside ploughed straight down the slope in a wet summer. Each furrow is a stream. Topsoil leaves for the river. Next year the same field feeds a weaker crop, so the farmer ploughs more land. That is a resource failing. Contour ploughing, cover crops and fewer animals on the veld slow the loss. Coal under the same district is a different case: once burnt, that seam is gone, so the question is what the income is used for, not how to grow the coal back. Sunlight on a roof does not have that limit. The theory is the refill time.

Before any working — hunt first
Given
Numbers and units already in the sentence: 11 · 1 · 240 m · 1 · 180 m · 1 · 310 m · 3 cm · 1 · 50 · 000 sheet · 1.5 km · 1 · 500 m · 60 m · 60 / · 1 · 500 · 1 in · 25 · 3 cm. Copy each one into a column. A name without a number is not given.
Missing
After you copy the given, the letter that still has no number is missing. The paper is pointing at: which is 1. Circle that word — that is the missing variable.
Find
We are required to find: which is 1. Write that as a symbol on the left, with a question mark, before you touch a formula.
Calculate
What we need to calculate: Mapwork. Then substitute the given, one line at a time, to get which is 1.
In other words — as if you have never seen this before
Mapwork. A cross-section is the side view along a line you choose on the contour map. You transfer each contour height onto a graph and join the heights. Gradient is the steepness: vertical difference divided by horizontal distance. Intervisibility asks whether one point can see another. If a hill rises above the straight line of sight, the view is blocked. Vertical exaggeration on the cross-section makes slopes look steeper than they are, so you say what exaggeration you used.

Worked theory
Worked theory. Two towers on a 1:50 000 sheet, with a ridge between them. The map distance is 4 cm, which is 2 km on the ground. The ridge is higher than both towers. The line of sight hits the ridge, so the towers cannot see each other, even though both are “on the map”. A cross-section makes that obvious in side view. If you forget to convert 4 cm with the scale, the gradient comes out as a cliff or as a pancake. The drawing is the test of whether the numbers mean a real hill.

On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.

6 · 8 Marks · The atmosphere
Geography Grade 11. Use this case. A berg wind at the coast. Air descends off the escarpment toward the coast, warms as it sinks, and arrives hot and dry. Relative humidity crashes. A fire that would have crept in moist air runs. This is not a cold front. A cold front brings cloud and a wind change from the north-west, then cooler air. The berg wind is the descending air. A forecast that says “it will be hot so a storm is coming” has mixed the berg wind up with convection. In sentences, say what The atmosphere is doing here, from the situation to the result.

In other words — as if you have never seen this before
The atmosphere. Warm air rises at the equator, travels poleward high up, sinks around 30 degrees, and returns as trade winds. That is the Hadley cell. Similar cells sit in the mid-latitudes and at the poles. Where air rises, rain is common. Where it sinks, deserts are common. The spinning Earth bends the winds. A synoptic chart draws the result for one day: highs, lows, and the fronts between warm and cold air. In the southern hemisphere, air circles clockwise into a low.

Worked theory
Worked theory. The Namib and the equator. Air rises over the hot Congo basin and rain is heavy. The same air sinks over the west coast of southern Africa, so the Namib stays dry even though the sea is next door. Sinking air does not favour rain. On a winter synoptic chart, a low and its cold front cross the Cape. Ahead of the front the wind and the cloud change. Behind it the air is cooler. The chart is the cells and the fronts, drawn for Wednesday, not a new kind of atmosphere.

Worked theory. The Valley of Desolation near Graaff-Reinet, or any dolerite-capped hill in the Karoo. The dark cap resists weathering. The softer rock beneath wears back. The cap is left standing as a mesa, then a butte. A river in flood does the carrying. A rock that cracks from heat and cold has only been weathered until water or gravity moves the pieces. Calling every hill a volcano misses the cap-rock story, which needs no eruption.

Worked theory. Two South African places. Sandton has offices, clinics and schools close together. A former homeland town may have a lower income, a longer trip to a hospital, and many people sending wages home. The national GDP looks healthier than the town feels, because GDP averages the Sandtons with the towns. HDI moves when a clinic and a school arrive, even if no new mine opens.

Next year the same field feeds a weaker crop, so the farmer ploughs more land. That is a resource failing. Contour ploughing, cover crops and fewer animals on the veld slow the loss. Coal under the same district is a different case: once burnt, that seam is gone, so the question is what the income is used for, not how to grow the coal back.

Gradient is the steepness: vertical difference divided by horizontal distance. Intervisibility asks whether one point can see another. If a hill rises above the straight line of sight, the view is blocked. Vertical exaggeration on the cross-section makes slopes look steeper than they are, so you say what exaggeration you used.

Worked theory. Two towers on a 1:50 000 sheet, with a ridge between them. The map distance is 4 cm, which is 2 km on the ground. The ridge is higher than both towers. The line of sight hits the ridge, so the towers cannot see each other, even though both are “on the map”. A cross-section makes that obvious in side view. If you forget to convert 4 cm with the scale, the gradient comes out as a cliff or as a pancake. The drawing is the test of whether the numbers mean a real hill.

Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
07 / 07
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit. Write those three lines even if you are unsure of the arithmetic — blank pages score zero.
Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.

The answer names the situation, what changed, and the result. It does not stop at a heading.
7. A trap first-timers fall into
A common mix-up is to leave centimetres and metres mixed in one gradient, or to claim two points are visible because no building is drawn between them.

1. What is the question asking?

4. Step-by-step working
01 / 07
Step A — Read the question twice
Slow down. Circle the word that names the unknown. Underline every number and its unit. Do not grab a formula yet — first decide what the paper is actually asking.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.
02 / 07
Step B — Write the given in a column
Copy these onto the left of your page, one per line, with units: every number and its unit in the sentence. Mixing cm with m, or minutes with seconds, loses a method mark.
Why this step: A column with units stops you mixing cm with m, or minutes with seconds. Markers can also see you started correctly.

Development is income plus health plus education. GDP alone hides inequality. Core regions concentrate wealth. Peripheries supply them.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
05 / 07
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.

Worked theory. A hillside ploughed straight down the slope in a wet summer. Each furrow is a stream. Topsoil leaves for the river. Next year the same field feeds a weaker crop, so the farmer ploughs more land. That is a resource failing. Contour ploughing, cover crops and fewer animals on the veld slow the loss. Coal under the same district is a different case: once burnt, that seam is gone, so the question is what the income is used for, not how to grow the coal back. Sunlight on a roof does not have that limit. The theory is the refill time. What does this case show about Resources and sustainability?

Renewable resources, such as sunlight, wind and, if managed, forests and fisheries, refill. Non-renewable resources, such as coal and oil, do not refill on a human timescale. Soil is renewable only if erosion is slower than soil formation. Overstocking, ploughing down the slope and cutting all the trees make soil a wasting resource.

Warm air rises at the equator, travels poleward high up, sinks around 30 degrees, and returns as trade winds. That is the Hadley cell. Similar cells sit in the mid-latitudes and at the poles. Where air rises, rain is common. Where it sinks, deserts are common. The spinning Earth bends the winds.

Missing
After you copy the given, the letter that still has no number is missing. The paper is pointing at: What is the answer to keep for Mapwork. Circle that word — that is the missing variable.
Find
We are required to find: What is the answer to keep for Mapwork. Write that as a symbol on the left, with a question mark, before you touch a formula.

Why this step: First-timers chase the final number and leave the method blank. The memo still pays out for the idea and the substitution even when the last line is wrong.

Answer: Cross-section shows the side view. Gradient is rise over run, in the same units. A ridge above the line of sight blocks the view.
6. Check it like a marker
Does your answer appear as one of the options? Do the units match what was asked (m, N, J, °)? If you put the number back into the original equation, does it still hold? Estimate: is the size sensible?
7. A trap first-timers fall into
First-timers often grab the first formula they remember, mix units (cm with m, minutes with seconds), or drop a minus sign. Write the formula in words first: “this equals that, because…”

1. What is the question asking?
Read the question twice. Circle the unknown. Underline every number and unit. The paper is asking: What is the answer to keep for Resources and sustainability?
In other words — as if you have never seen this before
Renewable means it can recover. Non-renewable means it cannot, on our timescale. Soil is renewable only if erosion is held down.
2. What do we already know?
Copy these onto the left of your page, one per line, with units: every number and its unit in the sentence. Mixing cm with m, or minutes with seconds, loses a method mark.
3. Which method — and why this one?
Renewable means it can recover. Non-renewable means it cannot, on our timescale. Soil is renewable only if erosion is held down.
4. Step-by-step working
01 / 07
Step A — Read the question twice
Slow down. Circle the word that names the unknown. Underline every number and its unit. Do not grab a formula yet — first decide what the paper is actually asking.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.
02 / 07
Step B — Write the given in a column
Copy these onto the left of your page, one per line, with units: every number and its unit in the sentence. Mixing cm with m, or minutes with seconds, loses a method mark.
Why this step: A column with units stops you mixing cm with m, or minutes with seconds. Markers can also see you started correctly.
03 / 07
Step C — Name the method in words
Renewable means it can recover. Non-renewable means it cannot, on our timescale. Soil is renewable only if erosion is held down.
Why this step: If you can say the method in a sentence, you will pick the right formula. First-timers skip this and grab the first equation they remember.
04 / 07
Working
Renewable means it can recover. Non-renewable means it cannot, on our timescale. Soil is renewable only if erosion is held down.
Why this step: We only do one job per line so a marker can follow the marks — and so you can find a slip without starting over.
05 / 07
Step G — Sense-check the size
Ask: is this the kind of number a Grade 10–12 paper would want? A speed of 3 000 ms for a learner walking, or a probability bigger than 1, means a unit or algebra slip. Estimate first: round the numbers and do the sum in your head.
Why this step: Markers write ‘unrealistic’ in the margin when the method is right but the size is wild. A 10-second head check often finds a missing 10² or a unit that never changed.
06 / 07
Step F — Box the answer with its unit
Renewable means it can recover. Non-renewable means it cannot, on our timescale. Soil is renewable only if erosion is held down.
Why this step: A number without a unit is half a mark on a Physics paper, and a marker can miss a Maths answer that is buried in working.
07 / 07
Step H — What the marker is looking for
On an NSC memo you usually earn: (1) a method mark for naming the right formula or idea in words, (2) an accuracy mark for substituting the given numbers with units, (3) an accuracy mark for the boxed answer with its unit.

Worked theory. Two South African places. Sandton has offices, clinics and schools close together. A former homeland town may have a lower income, a longer trip to a hospital, and many people sending wages home. The national GDP looks healthier than the town feels, because GDP averages the Sandtons with the towns. HDI moves when a clinic and a school arrive, even if no new mine opens. Calling the whole of Africa “undeveloped” erases the Sandtons and the cities that function. The indicator you chose changes the sentence you are allowed to say.

Working
Income per person is one indicator. The Human Development Index adds health and schooling. A country can be rich in minerals and still unequal. Developed and developing are rough labels for that mix of income, health and education. The core-and-periphery idea says investment and skilled work gather in a few places, while other places supply labour and raw materials. Development is a pattern, not a prize given to a continent.

Before any working — hunt first
Given
Numbers and units already in the sentence: no numbers yet — only a name, a diagram, or a worded unknown. Copy each one into a column. A name without a number is not given.
Missing
After you copy the given, the letter that still has no number is missing. The paper is pointing at: which needs no eruption. Circle that word — that is the missing variable.
Find
We are required to find: which needs no eruption. Write that as a symbol on the left, with a question mark, before you touch a formula.
Calculate
What we need to calculate: Weathering breaks rock in place. Then substitute the given, one line at a time, to get which needs no eruption.
In other words — as if you have never seen this before

Working
A cross-section is the side view along a line you choose on the contour map. You transfer each contour height onto a graph and join the heights. Gradient is the steepness: vertical difference divided by horizontal distance. Intervisibility asks whether one point can see another. If a hill rises above the straight line of sight, the view is blocked. Vertical exaggeration on the cross-section makes slopes look steeper than they are, so you say what exaggeration you used.
