Which type of material rises?

• Material that is more dense

• Material that is less dense

• The density does not determine if particles will rise or fall

What is an example of convection currents

• Feeling the heat from a bonfire with your friends

• Touching a hot curling iron

• The movement of air in a circular motion in the atmosphere
