Question

Assertion (A): Rotation is the spinning of the earth on its axis from west to east once in 24 hours.

Reason (R): The earth is always tilted in the same direction as it moves round the sun.

विकल्प

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R does not explain A.

• A is true but R is false.

• A is false but R is true.

Answer 1

A is true but R is false.

Explanation:

• Assertion (A) is true: Rotation refers to the spinning of the Earth on its axis from west to east, and it completes one full rotation in 24 hours, which causes day and night.
• Reason (R) is false: The Earth's tilt remains roughly the same throughout the year, but the Earth does not maintain the exact same tilt direction as it moves around the Sun. The axis remains tilted at about 23.5° relative to the plane of the Earth's orbit, and this tilt causes the changing seasons. While the Earth’s axis stays pointed in the same direction throughout its orbit, the reason for the seasons is more due to the Earth's tilt and orbit around the Sun, not because the Earth maintains the same direction.
