Landforms Lessons 5 - 8

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces by natural processes, including chemical, physical, and biological actions.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of soil and rock from one location to another, while weathering is the process of breaking down materials without movement.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

What causes chemical weathering?

Back

Chemical weathering is caused by chemical reactions, often involving water, that dissolve or alter minerals in rocks.

Front

What is physical weathering?

Back

Physical weathering is the mechanical breakdown of rocks into smaller pieces without changing their chemical composition.

Front

What role do rivers play in erosion?

Back

Rivers can erode land by carrying away soil and rock as they flow, shaping valleys and landscapes over time.

Front

How do mountains change over time?

Back

Mountains can decrease in height due to weathering and erosion, which wear down the rock and soil.

Front

What is sedimentation?

Back

Sedimentation is the process of settling or being deposited as sediment, often in bodies of water.

Front

What is a landform?

Back

A landform is a natural feature of the Earth's surface, such as mountains, valleys, plateaus, and plains.
