Convection is...

• Heat transfer through electromagnetic waves.

• Thermal transfer by contact of two objects.

• Caused by convection currents in the Earth's atmosphere.

• Transfers heat by moving currents in liquids and gases.

What is heat?

• Heat is the same as temperature.

• Heat is how hot or cold something is.
