Changes in the Geosphere Unit 3 Review

Which events bring about this kind of change to the Earth's surface?

• weathering and erosion

• deposition and landslides

• volcanic eruptions and earthquakes

• floods and mudslides

Which solution can help reduce damage from landslides?

• People should build more houses in mountainous regions.

• Houses in mountainous regions should be empty during heavy rains.

• More trees should be planted to stop the mass movement of rocks and soil.

• Houses should be built using wood rather than concrete.

Which statement is true about the impact the slope of the land has on the speed of water and rate of erosion?

• The gentler slope causes the water to move faster, and less erosion occurs than on a steep slope.

• The steeper slope causes the water to move slower, and less erosion occurs than on a gentle slope.

• The gentler slope causes the water to move slower, and more erosion occurs than on a steep slope.

• The steeper slope causes the water to move faster, and more erosion occurs than on a gentle slope.

Which activity will likely cause the most soil erosion?

• growing vegetables to eat

• planting flowers in garden

• mowing the grass on the soccer field

• removing trees from a wooded area

What could have caused this?

• earthquake

• erosion

• flood

• landslide

What causes the change?

• deposition by water

• deposition by waves

• landslide due to gravity

• magma eruption from volcanoes

Which process is most responsible for the changed landform?

• deposition

• earthquake

• erosion

• volcanic eruption

What landform is represented by the image?

• volcano

• valley

• canyon

• cavern

Thousands of fish fossils discovered high in the Rocky Mountains most likely indicate that

• ancient sea levels were once high enough to cover the mountains.

• a large flood washed the fish up to the tops of the mountains.

• the mountains were once part of the sea floor that was pushed up by tectonic forces.

• the fish were inhabitants of an ancient stream that became frozen during the ice ages.

The discovery of fossilized coral reefs on land is evidence that

• salt water changes coral into fossils.

• the reefs formed in a freshwater lake.

• the sea level has changed over time.

• coral reefs can form on dry land.
