Unit 10: Weathering, Erosion, and Deposition Concept Check

The diagram below shows how a piece of rock was broken apart by natural causes.

Which natural process caused the rock to break apart?

• Water filled the space in the rock and caused the rock to dissolve.

• Rocks filled the space in the rock and split the rock because of the increase in weight.

• Water filled the space in the rock, froze, and expanded until the rock split.

• Sand filled the space in the rock, became wet, and expanded until the rock broke.

Along the inside walls of the Grand Canyon, there are rock layers that were formed at different times in Earth's history. There are 19 distinct layers that formed the land where the Colorado River now flows through the canyon. Which agent of erosion caused the Grand Canyon to form?

• Wind

• Water

• Ice

• Air

NGSS.MS-ESS2-4

Which question best describes deposition?

• The movement of sand by wind, water, and ice.

• The breaking down of rocks by water, wind, or ice.

• A process by which wind or water drops sediment in a new location.

• None of these

There are 30,577 kilometers of beaches in the United States. Many of these areas are prone to coastal erosion. Coastal erosion can have a financial impact on an area. Which is NOT a financial Impact caused by coastal erosion?

• Beach erosion makes beach homes unstable.

• Receding shorelines can reduce tourism.

• Increasing sand can alter the shoreline.

• Piers can become structurally unstable due to erosion.

A teacher explains that some changes to Earth's surface are caused by wind. Students are given stopwatches and instructed to change a rock by blowing air on it for five minutes.

Why will the rock remain unchanged after the five minutes?

• Wind cannot change the surface of a rock.

• Wind changes Earth's surface over a long period of time.

• The student needed to blow air on the rock for at least 10 minutes.

• Changes to the surface of Earth happen in a short time.

Students write conclusions after studying changes to Earth's surface. Which student did NOT write an accurate conclusion?

• Student 1: Some changes to Earth's happen over a long period of time.

• Student 2: Erosion, deposition and weathering are ways Earth's, surface can be changed over a long period of time.

• Student 3: Water, wind, and ice can change Earth's surface.

• Student 4: Changes to Earth by water, wind, and ice always happen quickly.

Students pour water into the end of a stream table full of sand to show the effect of erosion. The stream table is a model because --

• it is smaller than streams found in nature.

• the sand is not the same as that found in nature.

• it is used during science class.

• the teacher says that it is a model.

• Student 2

• Student 3

• Student 4
