Question

Monsoon winds influence a large extent of ___________.

• A. Eastern Asia
• B. Southern Asia
• C. Western Asia
• D. Northern Asia

Answer 1

The correct option is B Southern Asia

Monsoon winds influence a large extent of Southern Asia.

The monsoons usually happen due to the differential heating of land and water. You probably know that land heats faster than water. This change in heating leads to a difference in pressures, which in turn leads to currents. Thus, the changes in pressure conditions also affect the monsoons. Normally, there is high pressure in the tropical eastern-south Pacific Ocean and low pressure in the tropical eastern Indian Ocean. But as years have gone by, there has been a reversal in the pressure conditions. Therefore, the eastern Pacific has lower pressure. This periodic change in pressure conditions is known as Southern Oscillations or SO.
