Question

Name the three processes by which the Earth’s atmosphere is heated.

Answer 1

The three processes by which the Earth’s atmosphere is heated are:

1. Radiation: Heat is transferred from the Sun to the Earth and its atmosphere through radiation, which does not require a medium and can occur even in a vacuum.
2. Conduction: Heat transfers from the Earth’s warm surface to the lower layers of the atmosphere by direct contact.
3. Convection: The heated air particles in the lower atmosphere rise and pass their heat to surrounding air particles, transferring heat upward through circulatory movement.
