The Tamil Monsoons

Q.

Winter Rainfall In Tamil Nadu Is Caused By

1. Western disturbances.

2. North-east trade wind

3. Depression over the Arabian Sea.

4. Cold winds coming from Tibet.

Q. Tamil Nadu receives very less rainfall through the southwest monsoon because theblocks the monsoon winds from blowing over the state.

1. ocean currents
2. Western Ghats
3. tidal waves
4. Eastern Ghats

Q. In Tamil Nadu, the rainfall received through the southwest monsoon gradually decreases from __________ to _______.

1. West, East coast
2. East, West
3. South, North
4. North, South

Q. Assertion (A): Northeast monsoon is the return of the southwest monsoon as the retreating monsoon.

Reason (R): The southwest monsoon returns in the form of the northeast monsoon due to the Coriolis effects which deflect the monsoon winds back towards the south.

1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true and (R) is false.
4. (A) is false and (R) is true.

Q. Due to which of the following phenomena does the monsoon winds pass over India?

1. Coriolis effect
2. Ocean currents
3. Hurricanes
4. Cyclones

Q. The southwest monsoon winds are deflected to thewhen they pass through the Equator to enter northern hemisphere due to the.

1. left
2. Coriolis effect
3. right
4. ocean currents

Q. Which of the following statements is/are true about the Coriolis effect?

1. It occurs due to rotation of the Earth on its axis.
2. It occurs due to revolution of the Earth on its orbit.
3. It causes the winds blowing in the northern hemisphere to deflect to the right and the winds blowing in the southern hemisphere to deflect to the left.
4. It causes the winds blowing in the northern hemisphere to deflect to the left and the winds blowing in the southern hemisphere to deflect to the right.

Q. Why does the northeast trade wind become dominant when the Sun moves towards the Tropic of Capricorn from the Tropic of Cancer?

1. Because of the high pressure area created over Indian ocean and the low pressure area created over the south of the Bay of Bengal.
2. Because of the low pressure area created over Central Asia and the high pressure area shifted over to the north of the Bay of Bengal.
3. Because of the high pressure area created over Central Asia and the low pressure area shifted over to the north of the Bay of Bengal.
4. Because of the high pressure area created over Central Asia and the high pressure area created over the north of the Bay of Bengal.
