Water in Earth's Processes Study Guide

What is the name of the ocean north of North America, Asia, and Europe?

• Atlantic ocean

• Arctic ocean

• Indian ocean

• Pacific ocean

What does the sun do to maintain the amount of freshwater found on land in the water cycle?

• The sun causes salt water to filter through the fine soils on land and collect in large pools.

• The sun causes glaciers to transpire and release freshwater onto land.

• The sun causes freshwater to condense deep in the bottoms of lakes so that it never evaporates.

• The sun causes freshwater to evaporate from salt water and some freshwater precipitates back to the Earth.

Most of the Earth is covered in water. What percentage of this water is safe to drink?

• 1%

• 5%

• 10%

• 20%

How will the percentage change if temperatures on Earth continue to rise?

• Less that 97% of Earth's water will be salt water.

• Nearly all of Earth's available freshwater will disappear.

• Less than 2% of the Earth's water will be in the polar icecaps.

• Nearly all water from Earth's polar icecaps will become available freshwater.

The blue crescent shapes on the side of the Earth represent Earth's water bulging outward as high tide occurs at 2 places. As Earth turns, the two tides will...

• Remain on opposite sides of Earth, in line with the moon.

• Move toward each other until they form one large mega tide.

• Split in half, causing high tides to occur at 4 places.

• Grow smaller until there are no more high tides occurring on Earth.

Most of Earth's surface is covered by what?

• Rocks.

• Craters.

• Water.

• Ice.

Freshwater is water that contains little to no salt. Which of the following is the LEAST likely to contain freshwater?

• Glaciers.

• Lakes.

• Oceans.

• Rivers.

Approximately what percent of Earth's surface is covered in water?

• 2.5%

• 30%

• 71%

• 96.5%

What ocean is east of Asia and west of North America?

• Atlantic ocean

• Pacific ocean

• Indian ocean

Using Earth as the origin, identify the angle (in degrees) between the Sun and Moon during neap tide.
