U3 Geosphere Review

The diagram shows a change in a landform over many years. Which process is most responsible for the changed landform?

• deposition and landslide

• volcanic eruptions and earthquakes

• weathering and erosion

• floods and mudslides

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.

Examine the rock layers pictured below. Which layer is most likely the oldest?

• 1

• 3

• 5

• 7

Which would most likely need storm drains?

• a highway with wide shoulders

• a city street with concrete curbs

• a gravel road that has many farms

• a dirt road that runs through a forest

The diagram shows a map of a lake. Which labeled part on the map is an island?

• A

• B

• R

• T

A student lists some slow processes that change the structure of Earth’s surface. Which process did the student list incorrectly?

• deposition

• earthquake

• erosion

• weathering

The image shows a mushroom rock. What natural process is responsible for the shape of the rock?

• floods

• landslides

• volcanic eruptions

• weathering and erosion

How do weathering, deposition, and erosion work together to create new landforms?

• Erosion breaks rocks apart, weathering moves the broken rocks, and deposition puts the broken rocks in a new location.

• Weathering breaks rocks apart, erosion moves the broken rocks, and deposition puts the broken rocks in a new location.

• Deposition breaks rocks apart, weathering moves the broken rocks, and erosion puts the broken rocks in a new location.

• Weathering breaks rocks apart, deposition moves the broken rocks, and erosion puts the broken rocks in a new location.

A student examines the diagram of rock layers from a mountain that hold fossils. The diagram only shows rock layers with fossils. The student claims that the mountain was once another environment. Is the student correct, and why?

• No. All the organisms lived at the same time in the same environment.

• No. All the organisms lived at different times in the same environment.

• Yes. Layer C has a fossil of an organism that lived on the mountain, while layer B has a fossil of an organism that lived on land.

• Yes. Layer A has fossils of organisms that lived in water, while layer B has a fossil of an organism that lived on land.
