Question

Which of the following is true about the rotation of the earth?

Options

• The earth completes one rotation in 25:56:4.09 hrs

• The earth's axis passes through the poles

• The speed of rotation increases as we move towards the equator

• All of the above

Answer 1

All of the above

Explanation:

1. The Earth completes one rotation in approximately 23 hours, 56 minutes, and 4.09 seconds. This is known as a sidereal day, slightly shorter than the 24-hour solar day.
2. The Earth's axis indeed passes through the North and South Poles, around which the Earth rotates.
3. The speed of the Earth's rotation is fastest at the Equator. As you move towards the poles, the circumference of the Earth decreases, resulting in a lower rotational speed.
