q15. cyclones move anticlockwise in the northern hemisphere and clockwise in the southern hemisphere due to ______.

• difference in the pressure
• difference in the temperature
• coriolis effect
• gravitational force of moon on earth atmosphere
• ocean tides

Explanation:

The Coriolis effect is a phenomenon that causes moving objects (such as air masses in cyclones) to turn to the right in the northern hemisphere and to the left in the southern hemisphere. This results in cyclones moving anticlockwise in the northern hemisphere and clockwise in the southern hemisphere. The difference in pressure causes air to move towards the low - pressure center of a cyclone, but it is the Coriolis effect that determines the direction of rotation. Difference in temperature is more related to creating pressure differences rather than the rotational direction of cyclones. The gravitational force of the moon on the earth's atmosphere is very small compared to other forces acting on the atmosphere and is not responsible for cyclone rotation. Ocean tides are related to the gravitational pull of the moon and the sun on the oceans, not the rotation of cyclones.

Answer:

C. Coriolis effect
