S6E5 Weathering Erosion Deposition 2023

What is the process of laying down of eroded material called?

• Erosion

• Transportation

• Deposition

• Weathering

What is the movement of weathered material (sediment) from one place to another?

• Erosion

• Deposition

• Weathering

• Sedimentation

What role does gravity play in erosion?

• Gravity has no effect on erosion.

• Gravity pulls materials uphill, reducing erosion.

• Gravity pulls materials downhill, contributing to erosion.

• Gravity only affects water flow, not erosion.

What do physical and chemical weathering both do to rocks?

• Break rocks into smaller pieces.

• Make rocks more colorful.

• Increase the size of rocks.

• Change the chemical composition of rocks.

What is a triangular deposit of sediment that forms where a river meets a larger body of water?

• Delta

• Estuary

• Basin

• Floodplain

What is sediment?

• Small pieces of rock and soil that are moved by wind, water, or ice.

• Large boulders that remain stationary in rivers.

• Organic material that decomposes in soil.

• Liquid minerals found in oceans.

What is the term for the dropping off and settling of sediments to the bottom of a lake or river?

• Erosion

• Sedimentation

• Deposition

• Transportation

What is the process called that involves the breaking down of rocks into smaller pieces?

• Erosion

• Weathering

• Sedimentation

• Lithification

What is the difference between weathering and erosion?

• Weathering is the movement of rocks, while erosion is the breaking down of those rocks.

• Weathering is the breaking down of rocks, while erosion is the movement of those broken pieces.

• Weathering and erosion are the same processes that occur simultaneously.

• Weathering is the process of planting trees, while erosion is the removal of soil.

What is an example of physical weathering?

• Frost wedging, where water freezes in cracks of rocks and expands.

• Chemical dissolution of minerals in water.

• Soil erosion caused by wind.

• Formation of sedimentary rocks from compacted sediments.
