What forms as a result of the continuous cycle of heating and rising fluid?

• A thermal gradient

• A conduction path

• A radiation wave

• A convection current

What is the main cause of fluid becoming less dense near a heat source?

• Increase in pressure

• Decrease in temperature

• Gain of energy

• Loss of energy

What happens to the particles that are pushed back around in the convection current?

• They lose energy

• They gain energy again

• They stop moving

• They become solid

What is the final result of the convection process in a fluid?

• The fluid remains cold

• The fluid heats up completely

• The fluid becomes solid

• The fluid evaporates
