Science Unit 1 Review Constructive and Destructive Forces

A student notices that the face of a mountain near a Georgia community has been changing. Some rocks have begun to break off the side of the mountain. A student claims that this is caused by a destructive process. Is the student's claim correct? Why or why not?

• The student's claim is correct because the mountain is changing due to destructive process of sedimentation.

• The student's claim is correct because the mountain is changing due to the destructive process of erosion.

• The student's claim is incorrect because the mountain is changing due to constructive process of deposition.

• The student's claim is incorrect because the mountain is changing due to the constructive process of weathering.

Look at the experiment in the picture. What is the model trying to show?

• formation of a mountain through wind erosion

• formation of a delta through wind erosion

• formation of a sand dune through wind deposition

• creation of an island through wind deposition

What landform was formed by the deposition of silt and other materials by moving water?

• 
• 
• 
•

This is a diagram showing the formation of delta. Which claim is correct?

• This delta was created by a destructive process called erosion.

• This delta was created by a constructive process of sand being deposited by moving water.

• This delta was created by a constructive process caused by moving wind.

The picture shows a dam. A dam is a structure that is placed across a stream or river that controls the amount of water that is allowed to pass through.

What question are dams designed to answer?

• How can humans prevent droughts from occurring?

• How can the direction of water flow in a river be reversed?

• How can flood waters be contained to avoid property damage?

How could human interaction decrease the destructive force of hurricanes on coastal areas?

• create levees to control water flow

• research the impact of organisms in the Mississippi Delta region

• study storm drain management in the South American rainforests

• assess the effects of seismological activity on metropolitan areas

Select TWO examples of erosion:

• gravity pulling down heavy slabs of rock from the face of a cliff

• moving water smoothing the surface of a jagged rock

• the roots of a plant crumbling a cement driveway

• a glacier scraping pieces from the sides of a valley as it moves

• a river carrying and dropping soil downstream

Answer explanation

Read each answer carefully and look for clue words --- in this question, your clue words were "pulling down" (that's moving sediment to a different location) and "carrying."

This is a picture of a jetty. How does a jetty help to protect a coastline from erosion?

• It prevents the sea level from rising and removing sediment.

• It becomes a barrier against waves and currents.

• It deposits sand created by the weathering of the rocks.

• It forces sand to stay on the beach by increasing waves.

Answer explanation

The process that transport rocks, soils, and sediments to a different location is called __________.

**** look at key words transport / different location

• weathering

• erosion

• deposition

Answer explanation

Look at all these examples of erosion that you have learned!!!

A student creates a model to show the effects of weathering on a rock. The steps she takes to create her model are shown.

Which part of the model will most likely provide the student with useful data illustrating the effects of weathering on the rock?

• the size of the crack

• the shape of the clay

• the position in the freezer

• the temperature of the water
