Conduction, Convection and Radiation 1

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when faster-moving particles collide with slower-moving ones, transferring energy.

Front

Give an example of conduction.

Back

An example of conduction is burning your hand on a hot iron.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense fluid rises and cooler, denser fluid sinks.

Give an example of convection.

Back

An example of convection is a hot air balloon rising.

Front

What is radiation?

Back

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

Give an example of radiation.

Back

An example of radiation is getting a sunburn while spending the day on the beach.

Front

How does convection affect weather patterns?

Back

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

Front

What role does conduction play in cooking?

Back

Conduction is important in cooking as it allows heat to transfer from the stove to the pot and then to the food.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

How does convection occur in the mantle?

Back

Convection in the mantle occurs as magma heats up, becomes less dense, rises, cools down, and then sinks, creating currents that move tectonic plates.
