PAPER 1

CLIMATOLOGY

1 (a) (i) Sunshine recorder/Campbell strokes

[1]

(ii) Open area, clear of building and tress

Where there is enough sunlight

[1]

(iii) Air pressure/atmospheric pressure

[1]

(iv) It shows rain/fair weather/stormy weather/dry weather

It shows a unit measure in millibars/hpa

[1]

(b) (i) Isotherms

[1]

(ii) The temperature is highest at Equator/Temperature lower at south

or north of the equator/Lower temperature north/south of Tropics

It decrease from the Equator to the North (of Africa)

It decrease from equator to South of Africa

Temperature fairly equal over land and sea in the North

Temperature makes a large dip towards the South

It increases from north or south of the equator

Data: -26 ?C at Equator/ 15 ?C at North / South

[2]

(c) (i) East Wind/Easterly wind

[1]

(ii) a decrease in atmospheric pressure

An increase in air temperature/Hot temperature

About 1?C for every 100m descent increase in air temperature

Very strong wind will be experienced

[2]

(d) (i) Are lines on the map connecting places of equal/same air pressure/ Lines connecting places with same/equal air pressure on the map [1]

(ii) Cold dense air/cold air/cold heavy air

Clear sky/no cloud cover/sunny

No rainfall

Cold nigh/frost

Winds are light

[2]

(iii) Warm air

Air rises

Reaches Dew Point Temperature

Condensation takes place/water droplets form

Clouds form

[2]

2

ECOLOGY

2 (a) (i) Refers to when an area/land is turned into a desert/expansion

of a desert

[1]

(ii) Overgrazing

Marginal land/cultivated

[2]

(iii) Increased demand for firewood/increase demand for wood/

Infrastructure/housing/natural resources res. 1

Deforestation

Fewer trees and plants

Increased evaporation from the soil

Increased demand for food on marginal land with overgrazing

Fewer trees and plants

Increased evaporation from the soil

Quality of soil decreased

[3]

(iv) Sustainable farming methods encouraged.i.e. mixed cropping/ Crop rotation/organic farming/rotational grazing Trees should be planted faster than they are cut down/reforestation/ Afforestation/plant more trees Alternative energy sources, such as solar energy/HEP Encourage alternative building materials Education + supportive explanation Recycle + reuse + supportive explanation

(b) (i) Air pollution

(ii) Industries Motorcars/vehicles/traffic Power stations

(iii) Causes acid rain Contaminate water sources Disturb the ecosystem (ecological balance) poisoning fish Contaminate/damage lake water/fish Affects soil chemistry Acidification of ground water supply Damage trees Contaminate lakes

GEOMORPHOLOGY

3 (a) (i) A Divergent/ constructive plate boundary

B Shear/ conservative plate boundary/slip/transform/neutral

C Converging/destructive plate boundary

[3]

(ii) Subduction zone=Destructive boundary (C) converging

Fault= Conservative boundary (B)

Ridge= Constructive boundary (A)/ Diverging

[3]

(b) (i) Focus

[1]

(ii) Seismograph

[1]

(c) - Kills people

- Causes injures/ breathing problem + explanation

- Damage buildings and property of people/ people left homeless/

- Without basic amenities

- Highway and bridges collapse/transport routes damage communication

- Essential services disrupted

- People lose their income

- People lose their jobs

- Decaying bodies causes diseases

[3]

(d) (i) Weathering - Processes whereby rocks on the surface of the earth

are broken down into situ/without movement

[1]

Erosion

- Processes whereby weathered rock is broken down

And moved from place of origin to another area/

With Movement

[1]

(ii) Running water/flowing/wind/moving ice/removal of glacier

[1]

(iii) Water, sunshine, salt, minerals, heat/temperature

[1]

[15]

POPULATION GEOGRAPHY

4 (a) (i) The number of people per square kilometer (km?).

Number of people per given area

Number of population per square kilometer

[1]

(ii) A Amazon rainforest

High humidity

Too hot

Too much rain

Too many tropical diseases

[2]

(iii) B Himalayas/ Himalayas mountains Too mountains/too cold Too dry Thin/rocky soils Difficult to develop because of slopes Too cold

Or

Gobi desert

Extreme temperature

Infertile soil

Difficult to develop

[2]

(iv) X- East Coast of North America/East of North America

Y- Indian Sub-continent / India/ South Asia

[2]

(v) Developed communication

Many industries/ more jobs

Many services

Economic development/ many businesses

Commercial farming

[1]

(b) Increased birth rate/ higher birth rate

Improved farming methods/availability of food supplies

Better/improved health conditions/standards

Reduced infant mortality rates

Greater life expectancy /decreased death rate/lower death rate

Better machines/ technology

Improved communication links

Improved trade links

Political stability
