Conduction, Convection, and Radiation
- Conduction: This is the process where heat moves through direct contact. For example, when air particles touch warmer surfaces, they gain energy and heat up.
- Convection: This involves the movement of air. Warm air rises, and cooler air moves in to take its place, creating a cycle that helps distribute heat throughout the atmosphere.
- Radiation: The sun emits energy that travels through space and warms the upper atmosphere. This energy is absorbed by atmospheric particles, contributing to the overall heating.
