B) They bring rain and play an important role in the water cycle.
C) They clear up the Sky and make the atmosphere sunny.
D) None of the above

Answer 1

Hint: A monsoon is a seasonal shift in the prevailing wind's course. When the wind blows from the colder ocean to the much warmer landmass, it creates a massive sea breeze. This shift in the wind normally results in a major change in the weather in the region.

Complete answer:
Monsoon winds - A monsoon is a seasonal shift in the direction of a region's prevailing winds or strongest winds. Monsoons are responsible for rainy and dry seasons in most of the tropics. The Indian Ocean is most often associated with monsoons. Monsoons often blow from the cold to the warm.

The wind that brings heavy rains to southern Asia is known as the monsoon, as are the rains themselves. People wait for the rain to end during a monsoon. While heavy rain is often referred to as a monsoon in other parts of the world, the true monsoon only occurs in Asia.

Cause of Monsoon wind - The disparity in annual temperature trends over land and sea is the primary cause of monsoons. From the Tropic of Cancer to the Tropic of Capricorn, the Sun's apparent location in relation to the Earth oscillates. As a result, the low-pressure area caused by solar heating shifts in latitude.

Importance of Monsoon winds -
- In India, the monsoon rains replenish reservoirs and groundwater, which aids irrigation and boosts hydropower output. Furthermore, a good Monsoon season will reduce demand for subsidized diesel used to pump water for irrigation from wells, the ground, ponds, or rivers.
- Since cold air takes up more space than warm air, monsoon winds blow from cold to warm regions. In the winter, monsoons blow from the land to the sea, and in the summer, they blow from the sea to the land. The winters in India are hot and dry. The northeast monsoon winds bring no moisture with them.
- Increased rainfall also reduces the need for electricity and fuel to pump water for irrigation. The monsoon winds' capacity has recently been harnessed in order to increase power production. The fact that these types of energy are renewable is a plus.
- Ocean winds transport water and precipitate rain. It's a natural occurrence that occurs as part of the water cycle. Water is carried by the monsoon winds, and it rains. Thus monsoons bring rain and play an important role in the water.

Hence the correct answer is option ‘B’.

Note: The monsoon is responsible for about 70% of India's annual rainfall and decides rice, wheat, sugarcane, and oilseed yields such as soybeans. Agriculture employs more than half of India's 1.3 billion population and accounts for about 15% of the country's $2.5 trillion economy.
