Environmental Science Ch. 13 Review

Front

What happens to winds in the western Pacific Ocean during El Niño?

Back

Winds strengthen and push warm water eastward.

Front

What seasonal pattern shows increasing levels of carbon dioxide?

Back

Each year, the high carbon dioxide levels of winter are higher.

Front

Define climate in terms of atmospheric conditions.

Back

Climate is the average atmospheric weather in an area over a long period of time.

Front

What natural elements help reduce carbon dioxide in the atmosphere?

Back

Oceans, phytoplankton, and tropical rain forests.

Front

How long do CFC molecules remain active in the stratosphere?

Back

CFC molecules remain active for 60 to 120 years.

Front

What is the primary greenhouse gas that contributes to global warming?

Back

Carbon dioxide (CO2).

Front

What is the role of phytoplankton in the carbon cycle?

Back

Phytoplankton absorb carbon dioxide during photosynthesis, helping to reduce atmospheric CO2 levels.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of those conditions.

Front

What is the significance of the ozone layer?

Back

The ozone layer protects the Earth from harmful ultraviolet (UV) radiation.

Front

What are the effects of deforestation on carbon dioxide levels?

Back

Deforestation increases carbon dioxide levels by reducing the number of trees that can absorb CO2.
