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 Inter tropical
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.

1. Monsoon is
(a) A type of sea wave
(b) a seasonal reversal in wind direction
(c) very hot wind
(d) very cold wind

2. What is the full form of ITCZ?
(a) Intertrance Convergence Zone (b) Intertropical Convergence Zone
(c) Intertropical Capricorn Zone (d) Intertropical Conveyance Zone

3. The major cause of monsoon is the
(a) difference between annual temperature trends over land and sea
(b) difference between day and night temperature
(c) moisture in the atmosphere
(d) None of these.

4. Low Pressure region is created by
(a) solar heating (b) lunar cooling (c) moist wind (d) dry wind.

5. It rains when
(a) moist wind goes down (b) dry wind meets moist wind
(c) the air can no longer hold moisture resulting in precipitation
(d) annual temperature goes down.

6. meaning of latitude______________
a) the angular distance of a place north or south of the earth's equator, or of the equator of a celestial
object, usually expressed in degrees and minutes.
b) move or swing back and forth in a regular rhythm.
c) the action or process of precipitating a substance from a solution
d) Capricorn is considered an earth sign, negative sign, and one of the four cardinal signs. Capricorn is
said to be ruled by the planet Saturn.
