Question

What causes wind currents on the Earth?

• A. Rotation of the Moon.
• B. Change in seasons.
• C. Uneven heating between the equator and the poles.
• D. Gravitational pull of the Sun.

Answer 1

The correct option is C Uneven heating between the equator and the poles.

Regions close to equator get maximum heat from Sun. Air in these regions are hotter than other regions. The warm air rises up and cool air from other regions move towards equator. These winds blow from North and South towards the equator.
