Answer 1

Answer: (B), (C)

The correct options are
B Though Monsoon is a seasonal wind, it is greatly influenced by the trade winds.
C

Planetary winds transport heat or moisture across the globe.

Planetary winds exit across the globe and plays a crucial role in transporting heat and moisture across the world. But, this distribution of heat and moisture is not uniform. Trade winds are a type of planetary wind. They are not directly responsible for the Monsoon. Monsoon is a seasonal wind caused mainly by the differential cooling of land and sea. The Monsoon is influenced by south-east trades. It crosses the equator, and due to the Coriolis effect, it becomes south-west Monsoon over India. Himalayas were formed due to the process lithospheric plate movements and not due to planetary winds.
