REVIEW: Unit 2.2 Energy Transfer on Earth

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one place to another or from one form to another.

Front

What are the three main methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

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

Front

Define convection.

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light.

Front

What happens to warm air over land during the day?

Back

Warm air rises and is often replaced by cooler air from the sea.

Front

Why does a metal spoon get hot in boiling water?

Back

Metal is a good conductor of heat, so it transfers heat from the boiling water quickly.

Front

What is an example of conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in everyday life?

Back

Boiling water where the hot water rises and cooler water sinks.

Front

What is an example of radiation in everyday life?

Back

Feeling the warmth of the sun on your skin.
