Environmental Science Ch 13 Review

Climate in a region is

• the long-term, prevailing atmospheric conditions.

• the atmospheric conditions on a given day.

• determined only by seasonal daylight hours.

• never effected by ocean currents.

Rain frequently results whenever

• cool, moist air rises.

• warm, moist air rises.

• warm, dry air sinks.

• cold, dry air sinks.

Which of the following best descries the effect of a mountain range on the climate of a region?

• the coastal side of the range usually has high levels of rain

• a desert if often found on the inland side of the range

• average temperatures are lower at high elevations

• all of the above

Latitude strongly influences climate because ___ solar energy falls on areas closer to the equator

• less

• sometimes less

• the same amount of

• more

The thinning of the ozone layer

• occurs over both polar regions

• will take many years to reverse

• is related to seasonal changes

• all of these

An important property of air circulation is

• cold air and warm air have the same density

• cold air is denser than warm air

• warm air is denser than cold air

• air has no mass

Which of the following gases is MOST responsible for the greenhouse effect?

• water vapor

• methane

• oxygen

• nitrous oxide

A true statement concerning the physical properties of air is that

• warm air sinks towards the Earth's surface.

• warm air can hold more water vapor than cold air

• as air warms, the water vapor it holds condenses

• cold air rises in the atmosphere

The difference between global warming and climate changes is that

• climate change only occurs along the equator

• human-made chemicals such as CFCs do not influence global warming

• previous changes in climate were dramatic by very short-lived

• global warming is a consequence of climate changes

Which of the following statements related to global warming is NOT accurate.

• carbon dioxide levels have risen over the last 30 years

• only fossil fuels, not living plants, release carbon dioxide when burned

• global temperature and carbon dioxide levels are related.

• reforestation is not sufficient to slow global warming.
