Question

Assertion(A): As we move away from the surface of the Earth in the atmosphere, the temperature increases.

Reason(R): As we move away from the surface of the Earth, we are more close to the sun.

• A. A and R are true and R is the correct explanation of A.
• B. A and R are true, but R is not the correct explanation of A.
• C. A is true but R is false.
• D. Both A and R are false.

Answer 1

The correct option is D

Both A and R are false.

The explanation for the Assertion statement:

1. As we move away from the surface of the Earth in the atmosphere, the temperature decreases initially for some height because the pressure decreases
2. At very high altitudes we have very less air molecules as the atmosphere gets thinner, so the temperature will decrease at very high altitudes.

The explanation for the Reason statement:

1. Statement R depends on from which side of earth we are moving away. If we are moving away from earth which is facing the opposite side of the sun, then we will be moving away from the sun. So, this statement is also false.

So, we can see that both statements are incorrect.

So, the correct answer is (D) Both A and R are false.
