Changes in the Geosphere

Front

What is deposition?

Back

Deposition is the process where materials, like sand, are dropped off in a new location, such as when waves deposit sand to form a sandbar.

Front

What is erosion?

Back

Erosion is the process of moving soil and rock from one place to another, often by water, wind, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural forces like wind, water, and ice.

Front

What is a delta?

Back

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

Front

What is a volcano?

Back

A volcano is a mountain with an opening in Earth's crust through which magma, gases, and ash can escape to the surface.

Front

How do glaciers cause erosion?

Back

Glaciers cause erosion by scraping and grinding rocks as they move across the Earth's surface.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces to a different location.

Front

What role do rivers play in erosion?

Back

Rivers can carry away soil and rocks, causing erosion, especially when the water is fast-moving.

Front

What is an example of deposition in nature?

Back

An example of deposition is when a river slows down and drops off sediment, forming a delta.

Front

What natural forces contribute to weathering?

Back

Natural forces that contribute to weathering include wind, water, ice, and temperature changes.
