Lesson 2.1 Energy Transfer in the Atmosphere

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

How does thermal energy move between objects?

Back

It moves from objects of higher temperature to objects with lower temperature.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as sunlight.

Front

What is latent heat?

Back

Latent heat is the heat absorbed or released by a substance during a phase change, such as melting or boiling, without changing its temperature.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking, creating a cycle in the atmosphere.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.
