Question

Atmosphere maintain the temperature on the surface of earth because

• A. It contains water vapour in it
• B. It holds air, which is a bad conductor of heat
• C. It reflects the heat rays
• D. It absorbs the heat rays.

Answer 1

The correct option is B

It holds air, which is a bad conductor of heat

The correct option is option B

The explanation for the correct option:

1. The atmosphere keeps the temperature of the earth's surface constant because it is largely made up of air, which is a poor conductor of heat and so prevents heat from escaping from the surface.
2. Air molecules are apart to properly transport heat to another molecule.
3. Because air is a poor conductor of heat, much heat energy is transferred by conduction at the earth's surface.

Final answer: Atmosphere maintain the temperature on the surface of earth because it holds air, which is a bad conductor of heat.
