Canyon Formation Worksheet

Which processes most likely formed the canyon?

• weathering and erosion by a river

• weathering and erosion by wind

• weathering and erosion by ice

• deposition by a river

An example of _____ occurs when tree roots grow underneath sidewalks and eventually cause the concrete to crack.

• sedimentation

• weathering

• erosion

• deposition

Which statements are true about slow changes to Earth's surface? Select TWO correct answers.

• A. Slow changes to Earth's surface are caused by weathering, erosion, and deposition.

• B. Wind, water, ice, and gravity can cause weathering, erosion, and deposition of sediments.

• C. Volcanic eruptions cause slow changes to Earth's surface over millions of years.

• D. Earthquakes take millions of years to form.

• E. Landslides are the only cause of changes to Earth's surface.

Which of these images was caused mainly from wind deposition?

• [Image of cracked rock]

• [Image of a canyon]

• [Image of a glacier]

• [Image of sand dunes]

What are the three processes that involve the breakdown and movement of rocks and sediments?

• Weathering, Erosion, Deposition

• Melting, Freezing, Condensation

• Photosynthesis, Respiration, Transpiration

• Evaporation, Sublimation, Precipitation

Which explanation BEST describes how the canyon is MOST LIKELY formed?

• An earthquake caused the ground to open, and a river started flowing through it.

• The river weathered the land and caused erosion over the span of thousands of years.

• The rocks were deposited along the edge of the river and built up over time.

• The river weathered the land and caused erosion over the span of a few days.

Erosion is the process by which rocks and sediments are carried to a new location. All of these are responsible for causing erosion EXCEPT-

• a flowing river.

• sunlight.

• gravity.

• a glacier.

A delta is shown in the image, which is formed when a river slows down as it enters the ocean. Which change to Earth's surface over time created the delta?

• Deposition

• Erosion

• Weathering

• A glacier

This question has two parts. First, answer Part A and then answer Part B. Part B: Which statement BEST supports the answer to Part A?

• The formation of the delta occurs due to wind depositing sediments.

• The delta formation occurs due to ice depositing sediments from a glacier.

• The formation of the delta occurs due to water depositing sediments from a river.

• The formation of the delta occurs due to ice breaking the land apart over time.

Ice wedging causes rock to break down over time. This process is called-

• weathering

• erosion

• deposition

• glacier
