2. Qn Proposed Answer Remarks
1(a)  Destructive plate margin/ Convergent plate margin
 Oceanic plate pushing against Continental plate
 Denser Oceanic plate subducts
 Oceanic plate melts, rises through crack in the
continental crust, forming volcanoes
 Continental plate bends and folds, forming fold
mountains
Must clearly include
both landforms at the
margins
1(b)  X is the Mid-Atlantic Ridge
 Two oceanic plates diverge / move apart
 Plates fracture and break up
 New mantle rises, forming new land.
 Sea floor spreads
 Underwater ridge is formed
Include any 1
landform highlighted
1(c)  San Francisco is very near San Andreas Fault
 Transform Fault
 Plates slide in opposite directions
 Slipping causes release of large energy waves
 Earthquakes devastate the cities nearby

3. 1(d)  Low viscosity lava is ejected, flows out rapidly
 Layers build up over time, forming low height, gentle slopes
1(e) Para 1
 Explain the given factor
 Example of this factor in a real world
Para 2
 Identify and explain an alternate factor
 Example of this factor in a real world setting
Para 3
 Explain which factor has a more significant
 Reinforce your stand

4. 2(a)  Orographic / Relief rain
 Hot air picks up moisture over sea
 It is pushed up the mountain
 It cools rapidly and rains as it reaches dew point
 Rain falls on the windward side
 When the air crosses the mountain. It is devoid of
moisture, there is no rain on the leeward side
2(b)  Country X experiences the SW monsoon
 Monsoon winds start at the S. Hemisphere
 Cool wind rushes towards the tropics
 Coriollis effect causes it to deflect
 Wet humid wind across the Indian ocean hits
landfall, dropping rain on country X.
2(c)  Flooding
 Sudden downpour
 Heavy, intense, sustained
 Lowland areas / drainage systems unable to cope
 Water cannot be directed out fast enough

5. 2(d)  Convectional rain
 Insufficient tall relief to build relief rain
2(e) Para 1
 Explain given factor ‘Monsoon Rain’
 Impact of monsoon
 Duration
 Type of monsoon
Para 2
 Highlight the key problems
 Link to Indian sub-continent
Para 3
 Highlight the potential benefit
 Link to Indian sub-continent

6. Section
B

7. 3(a)  Rice and Wheat gradually increase
 500 million (1900) to 2500 million (2015)
 Wheat 250 million (1900) to 3000 million (2015)
 Corn rapid increase
 500 million (1900) to 4500 million (2015)
 Increase demand for GM corn
 Corn syrup, animal feed, cereals.
3(b)  DC meat increase (1000 million to 2000 million
in 1990)
 Fall in 2015
 Quest for health, less meat protein
 LDC rapid rise
 (500 million to 2500 million in 2015

8. 3(c)  Malnutrition : insufficient intake of necessary
nutrients
 Result in illness and stunted growth
 Common in LDC with low disposable income
 Loss of educational opportunity due to illness
 Loss of employability due to regular sickness.
3(d)  Global warming increases temperature
 Larger areas of temperature areas warm up and
can plant crops.

9. 3(e) Para 1
 Explain what is GM food
 How is GM derived
 Example of GM food
Para 2
 Benefit of GM food
 LDC benefit
 DC benefit
Para 3
 Problems of GM food
 LDC & DC
Para 4
 Assessment of benefits vs problems
 Viability of GM
