Unit 4 - Changes to Earth's Surface

Front

What is deposition in the context of Earth's surface changes?

Back

Deposition is the buildup of land by the settlement of sediment and soil in a new location.

Front

What natural process is most likely responsible for the formation of a valley?

Back

Moving water is most likely responsible for the formation of a valley.

Front

How does water contribute to deposition?

Back

Water in a river slows down and drops off sediments to form a delta.

Front

What are dunes and how are they formed?

Back

Dunes are hills formed by wind blowing, moving, and depositing sand.

Front

What does the term weathering refer to?

Back

Weathering refers to the process of breaking apart rocks and minerals.

Front

What is erosion and how does it differ from deposition?

Back

Erosion is the process of moving sediment from one location to another, while deposition is the settling of that sediment in a new location.

Front

What role do rivers play in shaping the Earth's surface?

Back

Rivers shape the Earth's surface through processes like erosion and deposition, creating features such as valleys and deltas.

Front

What is the difference between mechanical and chemical weathering?

Back

Mechanical weathering involves the physical breakdown of rocks, while chemical weathering involves changes in the chemical composition of rocks.

Front

How do glaciers contribute to changes in the Earth's surface?

Back

Glaciers erode land as they move, carving out valleys and depositing sediments as they melt.

Front

What is a delta and how is it formed?

Back

A delta is a landform created at the mouth of a river where sediment is deposited as the river slows down.
