Atmosphere and Heat Transfer

Front

What is convection?

Back

Convection is the process of heat transfer through the movement of fluids (liquids and gases). In convection, warmer, less dense air rises, while cooler, denser air sinks.

Front

Where is the ozone layer located?

Back

The ozone layer is located in the stratosphere, which is the second layer of the Earth's atmosphere.

Front

Which heats up faster, land or water?

Back

Land heats up faster than water because it has a lower specific heat capacity.

Front

What happens to temperature as you go higher in the troposphere?

Back

As you go higher in the troposphere, the temperature decreases.

Front

What are the properties of cold air?

Back

Cold air is more dense and has more pressure than warm air.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs in solids where heat is transferred from one molecule to another.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight, which can travel through a vacuum.

Front

What is the troposphere?

Back

The troposphere is the lowest layer of the Earth's atmosphere, where weather occurs and where temperature decreases with altitude.

Front

What is the role of the stratosphere?

Back

The stratosphere contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

How does air pressure change with altitude?

Back

Air pressure decreases with increasing altitude because there is less air above you.
