Read the following passages carefully:
Passage 1:
What causes the monsoon? The monsoon, which is essentially the
seasonal reversal in wind direction, causes most of the rainfall received in
India and some other parts of the world. The primary cause of monsoons is the
difference between annual temperature trends over land and sea. The apparent
position of the Sun with reference to the Earth oscillates from the Tropic of
Cancer to the Tropic of Capricorn. Thus the low pressure region created by
solar heating also changes latitude. The northeast and southeast trade winds
converge in this low pressure zone, which is also known as the Intertropical
Convergence Zone or ITCZ. This low pressure region sees continuous rise of
moist wind from the sea surface to the upper layers of the atmosphere, where
the cooling means the air can no longer hold so much moisture resulting in
precipitation. The rainy seasons of East Asia, sub-Saharan Africa, Australia
and the southern part of North America coincide with the shift of ITCZ towards
these regions.
