Monsoon Zone

Monsoons are driven by wind direction changes due to differential heating of land and sea. In winter, high pressure over land causes dry winds, leading to droughts. In summer, low pressure draws moist ocean air inland, causing heavy rains. While monsoons are vital for agriculture, they also bring floods and cyclones. The cycle ends as temperatures drop, reversing the winds.

What primarily causes the formation of monsoons?

• The strength of the wind

• The direction of the wind

• The temperature of the ocean

• The humidity in the air

During winter, why does the land in Asia cool faster than the surrounding seas?

• Because the seas are warmer

• Because the land loses heat more quickly

• Because the land absorbs heat more effectively

• Because the land is at a higher altitude

What triggers the change in wind direction during the onset of the monsoon?

• The increase in ocean temperature

• The decrease in land temperature

• The increase in humidity

• The difference in pressure between land and sea

What percentage of annual rainfall is typically released during the monsoon season?

• More than half

• More than 3/4

• Less than 1/4

• Exactly 50%

What are some of the negative impacts of the monsoon in regions like India, Bangladesh, and Pakistan?

• Increased agricultural yield

• Severe flooding and cyclones

• Milder temperatures

• Decreased humidity
