1. The document discusses wind systems near coastal areas, specifically land and sea breezes. It includes diagrams to label and explanations of how differences in air pressure over land and sea cause the formation of these breezes. 2. It also discusses the monsoon winds that affect India, including a diagram to label areas of high and low pressure. The explanation given is that during the summer, heated air rises over central Asia creating low pressure, while cold air sinks over Australia creating high pressure, causing winds to move from the high to low pressure areas and forming the summer monsoon winds for India.

1 (a) Study Figure 1A and 1B below which show the wind systems near coastal
area.
Figure 1A – Land Breeze
Figure 1B – Sea Breeze
(i) Label Figure 1A and 1B to show the formation of land and sea breezes. [4]
(ii) With reference to Figure 8, explain how sea breeze and land breeze are
formed. [4]

2. Figure. 2 shows the June and December monsoons that affect India.
Monsoon winds affecting India
Figure 2
Label on the map the areas of high and low pressure and explain how the
June (Summer) monsoon winds are formed because of this difference in
pressure.

Suggested Answer
Question 1 (i)
Qn 1(ii)
 In the day, the land heats up faster than the sea, resulting in lower pressure over the
land and higher pressure over the sea
 As wind moves from higher pressure to lower pressure, it results in the wind blowing
from the sea to the land to form a sea breeze
 At night, the land cools down faster than the sea, resulting in higher pressure over
the land and lower pressure over the sea
 It results in the wind blowing from the land to the sea forming land breeze

Question 2
Label on the map the areas of high and low pressure and explain how the June
monsoonwindsare formedbecause of thisdifference inpressure.
[6]
During the middle ofthe year,
land in central Asiais heatedup.
The air is warm and rises,
formingan area of low pressure over Asia at sea level.
In Australia, it is winterand the cold, dense air sinks,
formingan area of high pressure overAustralia at sea level.
Air movesfrom an area of high pressure to an area of lowpressure.
Therefore air movesfrom Australia to Asia.
As the windcrosses the equatorit is deflectedtothe right due to the Coriolis
Effect
