• Conduction

• Convection

Answer 1

The heat radiated by the earth in the form of long waves is called Terrestrial radiation.

Explanation:

Terrestrial radiation refers to the heat energy emitted by the Earth’s surface in the form of long-wave infrared radiation. After absorbing solar energy (insolation), the Earth re-radiates some of it back into the atmosphere. This outgoing radiation plays a key role in Earth’s heat balance and climate regulation.
