The questions

Question 101

[1 marks]River processes and landforms
Which of the following changes in a river channel is most likely to increase the amount of deposition taking place?
  1. AAn increase in the river's velocity.
  2. BAn increase in the channel gradient.
  3. CAn increase in the river's discharge.
  4. DA decrease in the river's velocity.

Question 102

[1 marks]River processes and landforms
As a meander loop develops over a long period of time, erosion narrows the neck of land between two loops of a river until the river cuts through it, leaving an abandoned loop behind. This cutting-through of the neck typically happens...
  1. Awhen deposition completely fills the main channel, forcing the river to find an entirely new course around the blocked loop.
  2. Bwhen a dam is built across the river and the still water behind it slowly buries the neck of land under sediment.
  3. Cduring a drought, when the river dries up completely and its reduced flow can no longer maintain the shape of either loop.
  4. Dduring a flood, when high water breaks through the narrowed neck.

Question 103

[1 marks]River processes and landforms
State the term for the crescent-shaped lake formed when a river cuts through the neck of a meander loop and the abandoned loop is sealed off by deposition.

Answer this when you sit the paper.

Question 201

[1 marks]Climate and weather hazards
Mean monthly maximum temperature is best defined as...
  1. Athe average of the daily maximum temperatures recorded during that month.
  2. Bthe temperature recorded at midday on each day of the month.
  3. Cthe highest temperature ever recorded in that month.

Question 203

[1 marks]Climate and weather hazards
State the type of air mass, given by its standard two-word meteorological name, that originates over a sub-tropical continental interior.

Answer this when you sit the paper.

Question 301

[1 marks]Hot deserts and ecosystems
Most of the world's hot deserts lie on the western sides of continents mainly because, along these coasts,...
  1. Acold ocean currents cool the air and the sub-tropical high pressure belt suppresses rainfall.
  2. Bwarm ocean currents increase evaporation over the sea, driving frequent onshore rainfall along the coast throughout the year.
  3. Cthe coasts lie directly in the path of seasonal monsoon winds that sweep in from the ocean bringing heavy, reliable rainfall.
  4. Dhigh mountain ranges immediately inland block rain-bearing winds from ever reaching the narrow coastal strip below.

Question 302

[1 marks]Hot deserts and ecosystems
Which of the following is an adaptation shown by many hot-desert plants to reduce water loss?
  1. Asmall, waxy or spiny leaves, which reduce water loss through transpiration.
  2. Bbroad, thin leaves with a large surface area, which maximise photosynthesis by capturing as much sunlight as possible.
  3. Cshallow roots that spread wide just below the surface, reaching only the moisture left after light overnight dew.
  4. Dcontinuous leaf growth throughout the year, regardless of the season or the amount of rainfall received.

Question 303

[1 marks]Hot deserts and ecosystems
State the term for animal behaviour of being active mainly at night, an adaptation that helps hot-desert animals avoid extreme daytime heat.

Answer this when you sit the paper.

Question 401

[1 marks]Energy resources
In a country's energy mix, coal's share of primary energy use fell from 62% in 1970 to 28% in 1990. State the percentage-point decrease.

Answer this when you sit the paper.

Question 403

[1 marks]Energy resources
Which of the following is an advantage of hydro-electric power (HEP) over thermal power?
  1. Ait uses a renewable resource and produces no smoke or greenhouse gas emissions.
  2. Bit produces large amounts of ash and other solid waste that must be disposed of safely away from the plant.
  3. Cit causes far more air pollution than a thermal power station, releasing smoke and gases straight into the atmosphere.
  4. Dit requires a continuous, reliable supply of coal delivered to the power station to keep the turbines running.

Question 501

[1 marks]Farming systems
A farm keeps 500 cross-breed cattle, 40 Jersey cows, 100 pigs and 400 chickens, alongside 300 hectares of maize, cotton, wheat and soya beans, producing beef, milk, eggs and maize seed. Which farming system is this?
  1. Aextensive ranching.
  2. Bshifting cultivation.
  3. Cmixed farming.
  4. Dmarket gardening.

Question 502

[1 marks]Farming systems
A 20 000-hectare farm keeps only 4 000 beef cattle, has no land under crops, and employs just 10 workers. State the name of this farming system.

Answer this when you sit the paper.

Question 503

[1 marks]Farming systems
On a farm systems diagram, System Y applies the same capital and labour inputs as System X but to a much smaller area of land, while still producing a similar total output. System Y represents...
  1. Asubsistence farming.
  2. Bshifting cultivation.
  3. Cintensive farming.
  4. Dextensive farming.

Question 601

[1 marks]Industrial location
In Africa south of the Equator, processing and manufacturing industries are most heavily concentrated in which area?
  1. Athe northern savanna belt, well away from any coast, port facility or established rail network.
  2. BSouth Africa and its neighbouring states, such as Lesotho and Swaziland.
  3. Cthe central Sahara desert region, far from any coastline, port or major transport route.
  4. Dthe deep interior of the Congo rainforest, well away from any coastal port or rail line.

Question 602

[1 marks]Industrial location
Three possible sites are proposed for a new food-processing factory: Site 1 is on the coast, close to a raw-material supply area, and linked to the market by both road and rail; Site 2 is inland, isolated, and not linked to any road or railway; Site 3 is inland, within a raw-material supply area near a market, but not connected to the road or rail network. Which site is the best location for the factory?
  1. ASite 2, even though it has no road or rail connections at all, since it is the most central of the three inland sites.
  2. BSite 1, since it is linked by both road and rail to raw materials and the market.
  3. CSite 3, since it lies within a raw-material area near a market, even though it has no road or rail connection either.
  4. Deither Site 2 or Site 3, since both lie inland and would therefore be cheaper to develop than a coastal site.

Question 603

[1 marks]Industrial location
A proposed factory site lies within a raw-material supply area and close to a market, but it is not connected to any road or railway. Why would this site most likely be rejected as a factory location?
  1. Athe site is too far from any market to sell its finished goods without spending heavily on distribution over the extra distance involved.
  2. Btransporting raw materials and finished goods would be costly and difficult without road or rail links.
  3. Cthe site has no available land left for construction once the raw-material and market areas surrounding it are excluded from the survey.
  4. Dthe site has no raw materials of its own nearby, so every input would still have to be brought in from another region entirely, adding extra cost and delay.

Question 703

[1 marks]Rural and urban settlement
Urbanization is best defined as...

  3. Cthe increase in the total land area of a country through gradual settlement of previously unoccupied regions.
  4. Dthe movement of people away from towns and cities back into rural areas in search of farmland.
