Earth and Changes Over Time- Unit 1

What type of landform is shown in the diagram?

• Volcano

• Natural Arch

• Canyon

• Mountain

Which statement BEST describes how the arch was formed?

• Ice formed and wore away the rock.

• Chemicals in the air dissolved the rock.

• Rivers and streams shaped the rock.

• Strong winds wore away the rock.

Over time, how will the roots of the plant MOST likely affect the rock?

• They will hold the rock in place.

• They will protect the rock from the rain.

• They will force the rock into the ground.

• They will break the rock into smaller pieces.

Over a long period of time, running water in a river erodes the riverbed. This erosion causes the river to

• stop flowing.

• create waves.

• move faster and cleaner.

• become deeper and wider.
