GeoScience SEMESTER 2 REVIEW

Which of the following would cause surface ocean water to have a higher salt content?

• a river flowing into the ocean

• the melting of sea ice

• high rates of evaporation and low rates of precipitation

• low rates of evaporation and high rates of precipitation

A microclimate is:

• A large-scale weather pattern affecting an entire country

• The climate of a small, specific place within an area as contrasted with the climate of the entire area

• A type of global climate zone

• A sudden change in weather over a large region

Once liquid water is formed in a cloud, what needs to happen for it to fall as rain?

• The water droplets must evaporate.

• The water droplets must freeze.

• The water droplets must grow large enough to overcome air resistance and gravity.

• The water droplets must turn into ice crystals.

What is causing global warming?

• Deforestation

• Burning of fossil fuels

• Volcanic eruptions

• Solar flares

Most of Earth’s atmosphere is composed of

• oxygen and hydrogen.

• hydrogen and nitrogen.

• nitrogen and oxygen.

• carbon and ozone.

Air temperature is higher at low altitudes than it is at high altitudes because:

• The air is denser and can hold more heat at lower altitudes.

• There is more sunlight at lower altitudes.

• The ozone layer is thicker at lower altitudes.

• Wind speeds are higher at lower altitudes.

A warm front is:

• a boundary where warm air replaces cold air

• a boundary where cold air replaces warm air

• a zone of high pressure

• an area with no weather changes

Topography can have an important impact on a location’s climate. A Rainshadow occurs when:

• Moist air rises over a mountain, cools, and drops precipitation on the windward side, leaving the leeward side dry.

• Mountains block all wind, causing both sides to be equally wet.

• Rain falls only on the leeward side of a mountain, making it wetter than the windward side.

• Mountains have no effect on rainfall patterns.

What is the type of tide that occurs when the Sun, the Moon, and Earth form a right angle?

• Spring tide

• Neap tide

• High tide

• Low tide

One possible source of Earth’s water is:

• Volcanic eruptions

• The Sun

• Wind erosion

• Earthquakes
