Changing Landforms

A teacher set up the model shown to represent the formation of a landform. What landform does this model most likely represent?

• Delta

• Cave

• Canyon

• Sand dune

Which of the following processes is not considered a rapid change to Earth’s surface?

• Volcanic eruption

• Earthquake

• Landslide

• Weathering

A canyon with tall, vertical sides is shown. Which of the following most likely led to the formation of this canyon?

• Rapidly moving water

• A hurricane

• Burrowing animals

• Volcanic activity

Wind, water, and ice change Earth’s surface. Which landform was most likely formed by the slow movement of glaciers?

• Arch

• River delta

• V-shaped valley

• U-shaped valley

What agent of change is most likely responsible for the formation of the land features labeled in the image?

• Water

• Wind

• Glaciers

• Mud

The process in which rock is broken down into smaller pieces is

• Erosion

• Weathering

• Deposition

• Compaction

When water enters the cracks in a large rock and freezes, the water expands. Over time, water freezing and thawing –

• erodes the large rock through a river

• weathers the rock into sediments

• deposits lava in a new place

• changes the rock into a glacier

A teacher built the model shown to explain how one type of landform is created. What landform does the model most likely represent?

• Landslide

• Sand dune

• U-shaped valley

• Canyon

The images show a river delta and sand dunes. Which statement best explains how the formation of deltas and sand dunes is similar?

• Both are formed by the movement of glaciers.

• Both are formed by water eroding sediments.

• Both are formed by wind weathering rocks.

• Both are formed be deposition of sediments.

Which pair of landforms are the result of the same agent of change?

Note: The agents are wind, water or ice.

• A canyon and V-shaped valley

• A U-shaped valley and delta

• A sand dune and cave

• A delta and sand dune
