Question

The equatorial and polar regions of the earth receive unequal solar heat. The convection current arising due to this is called:
A. Land Breeze
B. Sea Breeze
C. Trade Wind
D. Tornado

Answer 1

Hint: The convection current arising due to this phenomenon is a permanent east to west prevailing wind that flows in Earth’s equatorial region.

Complete Answer:Trade winds arise due to the unequal heating of the equatorial and polar regions of the Earth. The trade winds are winds that reliably blow east to west just north and south of the equator and they help ships travel west.

The trade winds blow towards the west because the Earth rotates on its axis. The trade winds can also be defined as air currents closer to the Earth’s surface that blow from east to west near the equator.

The trade winds have been used by the sailors for centuries. The sailors travelling from Europe or Africa used the trade winds to travel to North or South America, they used and still use the trade winds to shorten the sea journey when sailing west.

Therefore the correct answer is option C.

Option A - Land Breeze - Land Breeze is part of the local wind system characterized by a flow from land to water late at night.

Option B - Sea Breeze - Sea Breeze is part of the local wind system characterized by a flow from water to land in the morning.

Option D - Tornado - It is a violently rotating column of air that is in contact with both the surface of the Earth and a cloud.

Note: Coriolis Effect is a phenomenon that makes things (like wind, missiles, planes, etc.) traveling long distances around the Earth appear to move in a curve as opposed to a straight line.
