Question

Assertion (A): In the course of the earth's movement around the sun, the North Pole remains inclined towards the sun for a part of the year while the South Pole is tilted away from it.

Reason (R): The earth rotates on an inclined axis in an elliptical path around the sun.

Options

• 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

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

Explanation:

• Assertion (A) is true: As the Earth moves around the Sun, the North Pole remains inclined towards the Sun for part of the year, leading to summer in the Northern Hemisphere, while the South Pole is tilted away from the Sun, resulting in winter in the Southern Hemisphere. This tilt causes the changing seasons.
• Reason (R) is also true: The Earth rotates on an inclined axis and moves along an elliptical orbit around the Sun. The Earth's 23.5° tilt and the elliptical orbit contribute to the seasonal variations.
