Geography [1 Mark Question Answer]

Three chief types of winds are Trade winds, Westerlies, and Polar winds.

It is the belt of the low-pressure belt between 60°N – 70°N and 60° S – 70° S.

Altitude — The pressure also decreases with increasing altitude at the rate of 100 millibars in every 1000 meters of height gained.

Coriolis force — This force is created by the rotation of the earth as the winds in different belts deflect towards the right in the Northern hemisphere and to the left in the Southern hemisphere.

Two chief characteristics are that these provide clear weather and the winds blowing from the center towards outside in the clockwise direction.

Winds — Horizontal movements of the air from high pressure to low pressure areas are called winds.

Pressure Gradient — It is the rate of change of atmospheric pressure between two points on the earth’s surface.

Due to the rotation of the earth from west to east, the winds are deflected to the right e.g. the trade winds blowing from the north, to the south take north easterly direction.
