What causes the circulation of air in the atmosphere?

• Air in the atmosphere is heated by the sun and sinks to the ground.
• The ground is heated by the sun and then heats the air, causing the air to rise.
• Air loses heat to the ground and then rises upward to obtain more energy.
• The sun heats the clouds which forces the cooler air to move away and sink.

What is the definition of CONVECTION

• When heat transfers through waves.
• When heat transfers from objects that are touching.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• Heat traveling from the sun

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

Which of the following is an example of convection?

• A hair dryer is drying up your hair.

• When the AC or heater changes the temperature.

• When a car engine turns hot after being turned on.

• When you are making soup and the water is rising and lowering.
