Question

Assertion (A): The phenomena of perihelion and aphelion happen during a year.

Reason (R): This is due to the variation in the distance between the earth and the sun within the orbit.

Options

• Both A and R are true and R is the correct reason for A.

• Both A and R are true but R is not the correct reason for A.

• A is true and R is false.

• A is false and R is true.

Answer 1

Both A and R are true and R is the correct reason for A.

Explanation:

Perihelion and aphelion are phenomena that occur because the Earth’s orbit around the Sun is elliptical, causing the distance between the Earth and the Sun to vary during the year. When the Earth is closest to the Sun, it is perihelion; when farthest, it is aphelion. Thus, both assertion and reason are true and the reason correctly explains the assertion.
