Weathering, Erosion, and Deposition

What is a delta?

• A landform that forms at the mouth of a river where it meets a body of water, created by deposition of sediment.

• A type of cloud formation that indicates rain is coming.

• A geological feature formed by volcanic activity.

• A large body of saltwater that is partially enclosed by land.

What can cause weathering?

• Temperature changes

• Earthquakes

• Volcanic eruptions

• Tsunamis

What is weathering?

• The process of breaking down rocks and minerals by physical, chemical, or biological processes.

• The formation of new rocks from molten lava.

• The movement of rocks from one place to another due to erosion.

• The process of plants growing on rocks.

What is the process of sediment settling called?

• Transportation

• Weathering

• Deposition

• Erosion

How does ice contribute to erosion?

• Ice erodes land by melting and washing away soil.

• Ice can erode land by freezing and expanding in cracks of rocks, causing them to break apart.

• Ice contributes to erosion by creating rivers that flow over rocks.

• Ice has no effect on erosion.

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 creating new rocks, while erosion is the process of destroying them.

What happens during weathering?

• Rocks are melted into magma.

• Rocks are broken down into smaller pieces but do not move from their original location.

• Rocks are transported to different locations by wind and water.

• Rocks are transformed into soil through biological processes.

How do rivers contribute to erosion?

• Rivers can erode the land by carrying away soil and rocks as they flow.

• Rivers contribute to erosion by depositing sediment in lakes.

• Rivers prevent erosion by stabilizing the soil along their banks.

• Rivers only erode land during heavy rainfall.

Why is understanding weathering, erosion, and deposition important?

• It helps us predict weather patterns more accurately.

• It allows us to understand how landscapes change over time and the impact of natural forces.

• It is essential for improving agricultural practices.

• It aids in the development of new technologies.

What is sediment?

• Small pieces of rock, soil, and organic material that can be moved by erosion.

• A type of large rock formation found in mountains.

• A liquid substance that forms during heavy rainfall.

• A process of breaking down rocks into smaller pieces.
