Question

What are three ways that heat energy is transferred through the atmosphere?

Answer 1

Convection

Convection transfers heat through the air. As the air heats, it rises. Cooler air below moves in, heats up and rises. As the risen air cools, it becomes denser and falls. This circular flow of air creates a convection current.

Conduction

Conduction moves heat through a material. It keeps a fire going by spreading the heat through solid material.

Radiation

Radiation is the heat that we feel coming from a fire. It warms the air using heat waves that radiate out from the fire in all directions until it is absorbed by objects.
