Circulation of Earth’s Water & Atmosphere Flashcard

Front

What happens to air density when it gets colder?

Back

Air density increases when it gets colder.

Front

What causes distinct patterns of global winds?

Back

Distinct patterns of global winds are caused by the unequal heating of Earth's surface.

Front

What is the movement of air from areas of high pressure to areas of low pressure called?

Back

This movement is called wind.

Front

What is the layer of gases that surrounds the Earth?

Back

The layer of gases that surrounds the Earth is called the atmosphere.

Front

What is the transfer of heat through the movement of fluids due to differences in temperature called?

Back

This process is called convection.

Front

What is the relationship between temperature and air pressure?

Back

As temperature increases, air pressure generally decreases.

Front

What role does the sun play in the Earth's water cycle?

Back

The sun provides energy that drives the evaporation of water, which is a key part of the water cycle.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as winds, due to the rotation of the Earth.

Front

How does altitude affect air pressure?

Back

As altitude increases, air pressure decreases.

Front

What is evaporation in the context of the water cycle?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat.
