• Evaporation

In the winter, you lay on a rock that was warmed by the sun all day. How is the rock able to warm you up?

• The rock conducts heat to your body.

• The rock reflects sunlight onto you.

• The rock generates its own heat.

• The rock absorbs cold from your body.

How does the sun transfer heat?

• Conduction

• Convection

• Radiation

• Evaporation

Heat transfer through convection can be described as:

• The transfer of heat through direct contact

• The transfer of heat through electromagnetic waves

• The transfer of heat through the movement of fluids

• The transfer of heat through empty space
