What is convection?

Back

Convection is the transfer of heat through currents in fluids (liquids and gases). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas sink.

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through touch.

Front

What is radiation?

Back

Radiation is the transfer of energy through space in the form of electromagnetic waves. It does not require a medium to travel through.

Front

How does Earth receive energy from the sun?

Back

Earth receives energy from the sun primarily through radiation.

Front

What is an example of conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection?

Back

An example of convection is boiling water in a pot, where hot water rises and cooler water sinks.

What is an example of radiation?

Back

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

Front

What role does convection play in weather patterns?

Back

Convection helps to distribute heat in the atmosphere, leading to the formation of wind and weather patterns.
