This picture shows warm air rising and cool air falling in a cycle. This is an example of which process?

The Sun’s rays take about 8 minutes to reach Earth’s atmosphere. Which process describes the thermal energy transfer between the Sun and the Earth?

Radiation

When the temperature outside rises, the temperature of the air in the house rises as well. Why is the 2nd floor air warmer than the 1st floor?

Back

Convection. Warm air rises to 2nd floor.

This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

Chris has to build a fire to keep the campers warm. The heat transfer from the fire keeps the campers warm due to: Conduction, Convection, Radiation

The picture is a Bunsen burner heating a beaker of water. The arrows show the transfer of heat energy in the water. Which process is primarily responsible for the transfer of heat?

Convection

Front

In the water cycle, sunlight causes water to evaporate, rise to form clouds, fall as precipitation, flow into a body of water, and begin the cycle again. What type of energy transfer is occurring as the evaporated water rises? Options: Conduction, Convection, Radiation

What do both of these things have in common? A beaker is heated with a balloon attached to the top. When the water in a beaker is heated, the steam rises to inflate the balloon. When the air in a hot air balloon is heated, the hot air rises and lifts the balloon.

Back

In both instances, a balloon is inflated because of warm air rises and filling the balloon. Thus, convection takes place.
