Assertion (A): Earth radiates energy in longwave form. Reason (R): Shortwave radiation heats the atmosphere directly from above.

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

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

• A is true, but R is false.

• A is false, but R is true.

Assertion (A): The earth maintains its average temperature through heat balance. Reason (R): The insolation received by the Earth is equal to the energy radiated back to space.

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

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

• A is true, but R is false.

• A is false, but R is true.
