Time allowed: 1 hour
Maximum marks: 100
lowest temperature in January, about 18°C (1)
annual range of temperature reaches 41°C (1)
distinct seasonal difference in temperature (1)
low annual rainfall as 142mm (1)
mainly concentrates in summer (1)
Explanation: (max. 5 marks)
Area B is located in the inland / continental interior (1)
continentality (1)
land heats up and cools down quickly in summer and winter respectively (1)
causing a large annual range of temperature (1)
far away from the sea (1)
wet onshore summer monsoons cannot reach there (1)
no maritime effect (1)
in winter, dry offshore winds from the interior (1)
resulting in scarce annual rainfall (1)
local convection rain is the major source of rain in summer (1)
due to its high temperature / high evaporation rate (1)
forming strong vertical air currents / convection current (1)
due to the rapid population growth (1)
increasing demand for food and other resources (1)
grow more crops and rear more livestock (1)
exceeding the low carrying capacity of the land (1)
leading to the problem of overcultivation and overgrazing (1)
the soil moisture and nutrients are exhausted / soil fertility drops (1)
vegetation cover fails to grow (1)
the soil becomes lack of protection leading to soil erosion (1)
land becomes unproductive and turns into desert-like environment as desert (1)
decrease in farmland and crop yield (1)
desertification contributes to the bury of farmland, which reduces the farmland area (1)
due to the increasing sandstorms brought by desertification, the sandstorms affect the
crop growth or even contribute to the crop failure (1)
economic loss is caused (1)
public facilities and homes are buried by moving sand dunes (1)
the loss of historical relics contribute to the loss of tourist spot and hence the income
from tourism (1)
threaten public health (1)
the decrease in freshwater supply brought by desertification may threaten people's
survival (1)
loss of historical relics and hence the history of the place (1)
when historical relics are buried under the sand due to the spread of deserts (1)
(4 marks; point + elaboration – 2 marks)
green belt / afforestation / windbreak (1)
(ii) Effective:
roots help bind the soil together (1)
prevent the sandy soil from moving outward to non-desert area / semi-arid area (1)
less capital and technology are required (1)
even Inner Mongolia provincial government is able to implement (1)
Ineffective:
more human inputs are required when growing vegetation cover in desert-like such harsh
environment (1)
causing difficulties for provincial government to maintain the green belt when they are
poor / lack of capital (1)
illegal logging may happen when the area covered is too large (1)
lower the effectiveness of green belt / windbreak to prevent the movement of sand
unstable and scarce water supply (1)
making the growing of vegetation cover more difficult (1)
(4 marks; accept other possible answers)
(iii) control grazing / cultivation / logging (1)
avoid over-exploitation of land / avoid the human activities from exceeding its low
carrying capacity to maintain the productivity (1)
straw checkerboard (1)
fix the sand dunes to avoid them from spreading to non-desert areas / semi-arid areas (1)
develop renewable energy e.g. solar energy / wind power / biogas (1)
avoid the problem of overcutting of firewood (1)

The climate of deserts is usually of low annual rainfall, because it is located at (a) where
the air sinks. The formation of (b) is hindered, which lowers the chance of precipitation.
(c) near the surface causing turbulence or convection forms strong winds, which facilitates
the formation of sandstorms.
Due to desertification and sandstorms, the lower (d) contributes to less photosynthesis,
which affects the growth of crops. More wind erosion blows away the (e), resulting in poor
soil fertility which further affects the crop growth.
As the soil is formed by _(f), the soil is of low nutrients and (g) capacity.
Inappropriate farming methods such as overuse of fertilizers and (h) in North China lead to
worsening of desertification. It is because original high summer temperature leads to high
evaporation which draws the salt underneath to the soil surface. This problem is known as (i).
Most of the measures combating desertification are of (j), which requires a lot of capital
persistently. However, most provinces in North China are of low GDP capita, which exerts great
difficulties to enforce.
Section C True or False (10 marks; 2 marks each)
Write "T" for the statement(s) which is/are true. Write "F" for the statement(s) which is/are
false. For the false statement(s), underline the mistake you have found on the answer sheet.
[Remark: only 1 mistake in one statement]
The daily range of temperature in deserts is large because of the presence of cloud cover.
2. Soil in deserts is known as saline soil when it contains little mineral.
3. Sandstorms are common in humid regions.
4. Rapid population growth in North China has led to the misuse of land resources.
5. In China, sandstorms occur most frequently in winter because of the influence of winter
