Question

Assertion (A): Greenhouse gases inhibit the escape of total radiation by absorbing the long wave infrared radiations and reflecting them back towards the earth.

Reason (R): Greenhouse gases increase the temperature of earth.

Options

• Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

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

• Assertion (A) is true but reason (R) is false.

• Both assertion (A) and reason (R) are false.

Answer 1

Both assertion (A) and reason (R) are true, and reason is the correct explanation of assertion.

Explanation:

Greenhouse gases absorb outgoing long-wave infrared radiation and send some energy back toward Earth’s surface. This trapping of heat raises Earth’s temperature.
