Earth's Atmosphere and Environmental Issues Flashcard

Front

What is the main reason for variations in air pressure across different regions of Earth?

Back

The uneven heating of Earth's surface causes variations in air pressure.

Front

Which layer of Earth's atmosphere is closest to the surface?

Back

The troposphere.

Front

What environmental change is likely as the ozone layer recovers?

Back

Decreased levels of harmful ultraviolet radiation reaching Earth's surface.

Front

How does temperature change in the mesosphere with altitude?

Back

Temperature decreases as altitude increases.

Front

What causes the temperature to increase in the stratosphere as altitude increases?

Back

The absorption of ultraviolet radiation by ozone.

Front

What is the role of the ozone layer in Earth's atmosphere?

Back

The ozone layer absorbs harmful ultraviolet radiation from the sun.

Front

What is the significance of the troposphere?

Back

It is the layer where weather occurs and where we live.

Front

How does air pressure affect weather patterns?

Back

Variations in air pressure lead to different weather conditions.

Front

What happens to temperature as you move from the troposphere to the stratosphere?

Back

Temperature increases with altitude in the stratosphere.

Front

What is the primary cause of ocean acidification?

Back

Increased levels of carbon dioxide in the atmosphere.
