What is convection?

Back

Convection is the type of heat transfer that occurs in fluids, such as warm air rising and cold air sinking.

Front

What happens to air density as temperature increases?

Back

As temperature increases, air density decreases.

Front

What is the main reason cold air sinks?

Back

Cold air sinks because it is denser than warm air.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves.

Front

Which layer of the atmosphere is closest to Earth?

Back

The Troposphere.

Front

What is the role of the Stratosphere?

Back

The Stratosphere contains the ozone layer, which protects Earth from harmful UV radiation.

Front

What is the Mesosphere known for?

Back

The Mesosphere is where most meteors burn up upon entering Earth's atmosphere.

Front

What is the Thermosphere?

Back

The Thermosphere is characterized by high temperatures and is where the auroras occur.
