Question

On the Earth, winds from the North pole and the South pole blow towards the equator. What can we understand from this?

• A. Earth is spherical in shape.
• B. It is hotter in and around the equator as compared to the poles.
• C. It is hotter in and around the poles as compared to the equator.
• D. Wind cannot flow from the East or the West.

Answer 1

Answer: (A), (B)

The correct options are
A Earth is spherical in shape.
B It is hotter in and around the equator as compared to the poles.

Winds that are cold usually shows lateral (sideways) movement while the ones that are warm usually shows vertical movement. Since the Earth is spherical in shape, the Sun rays falling on the Earth is overhead at the equator and slant at the poles. So, the equator and its surrounding regions are hotter than the rest of the earth. Because of this, winds from the poles (the north and the south) flow towards the equator.
However wind at times can flow from East and West too.
