Erosion and Weathering: Science 5.1

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind, water, and ice.

Front

What is weathering?

Back

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

Front

What are the main types of erosion?

Back

The main types of erosion are water erosion, wind erosion, ice erosion, and gravity erosion.

Front

What is a meandering river?

Back

A meandering river is a river that has many curves and bends, often forming loops as it flows.

Front

What role does gravity play in erosion?

Back

Gravity causes mass movements such as landslides, mudslides, and rock slides, contributing to erosion.

Front

What is frost wedging?

Back

Frost wedging is a type of physical weathering where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

How does water cause erosion?

Back

Water causes erosion by flowing over land, carrying away soil and sediment, and shaping landscapes.

Front

What is the difference between erosion and weathering?

Back

Erosion involves the movement of soil and rock, while weathering is the process of breaking down rocks without movement.

Front

Can weathering produce new soil?

Back

True, weathering can break down rocks into smaller particles that contribute to the formation of new soil.

Front

What is the most common cause of erosion?

Back

Water is the most common cause of erosion, as it can transport large amounts of soil and sediment.
