Weathering Erosion Deposition

What is an example of erosion caused by wind?

• Sand dunes being shaped and moved by strong winds.

• Rivers carving valleys through mountains.

• Glaciers grinding down rock formations.

• Rainwater washing away soil from hillsides.

What happens during erosion?

• Sediments are transported by natural forces such as water, wind, or ice.

• Sediments are created from the breakdown of rocks.

• Sediments are deposited in layers on the ocean floor.

• Sediments are transformed into fossils over time.

What is deposition?

• The process where sediments are dropped or settled in a new location after being transported.

• The process of eroding rocks and soil by wind or water.

• The process of transforming liquid water into vapor.

• The process of breaking down rocks into smaller pieces through weathering.

What is erosion?

• The process that moves sediments from one place to another.

• The process of breaking down rocks into smaller pieces.

• The process of water evaporating from the surface of the earth.

• The process of plants growing in a specific area.

How does acid rain affect rocks?

• It makes rocks more colorful.

• It causes chemical weathering by dissolving minerals in rocks.

• It strengthens the rocks' structure.

• It has no effect on rocks.

Give an example of physical weathering.

• A rock breaking into fragments due to freeze-thaw cycles.

• A tree root splitting a rock apart.

• Chemical reactions causing rock dissolution.

• Erosion caused by wind carrying sand particles.

How do glaciers contribute to erosion?

• Glaciers can pick up and transport large amounts of sediment as they move.

• Glaciers primarily cause erosion through melting ice.

• Glaciers do not affect the landscape significantly.

• Glaciers only erode rock through chemical processes.

What is frost wedging?

• A type of physical weathering where water seeps into cracks, freezes, and expands, breaking the rock apart.

• A process where ice forms on the surface of water bodies during winter.

• A method of soil erosion caused by heavy rainfall.

• A technique used in agriculture to improve soil fertility.

What is chemical weathering?

• The process that changes the physical structure of rocks without altering their chemical composition.

• The process that changes the chemical composition of rocks, often through reactions with water or acids.

• The process of breaking down rocks into smaller pieces through mechanical forces.

• The process that involves the transportation of sediments from one location to another.

What is the impact of vegetation on erosion?

• Vegetation helps to anchor soil and reduce erosion by wind and water.

• Vegetation increases soil erosion by trapping moisture.

• Vegetation has no impact on erosion.

• Vegetation causes soil to become overly saturated and erode faster.
