Unit 4 Part 1 Review

What is the difference between weathering and erosion?

• Erosion breaks down the rocks, and weathering carries the broken pieces away.

• Erosion carries broken pieces away, and weathering builds the pieces back up into another land mass.

• Weathering carries broken pieces away, and erosion builds the pieces back up into another land mass.

• Weathering breaks down rocks, and erosion carries the broken pieces away.

The tallest sand dunes in North America are found in Great Sand Dunes National Park and Preserve in Colorado. These dunes were formed from the sand at the bottom of a dry lake bed. Which of the following agents is most likely responsible for the formation of the sand dunes?

The process by which igneous rocks are formed...

• heat and pressure

• melting and cooling

• weathering and erosion

The process by which metamorphic rocks are formed...

• heat and pressure

• erosion and deposition

• melting and cooling

Deposition changes the Earth’s surface because bits of broken rock and soil _____

• stop rivers from flowing.

• make rich farmlands.

• are dropped in new places.

• move very slowly.
