Unit 4: Changes in the Earth's Surface

Front

What is a constructive process in geology?

Back

A constructive process is a natural process that builds up landforms, such as volcanic eruptions that create new islands.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind, water, or ice and transported to another location.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or deposited, such as sand being dropped on a beach by waves.

Front

What is weathering?

Back

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

Front

How do volcanic eruptions contribute to landform changes?

Back

Volcanic eruptions can create new landforms by depositing lava that cools and solidifies into rock.

Front

What is an example of a destructive force?

Back

An example of a destructive force is erosion, which wears away landforms over time.

Front

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

Back

Glaciers can carve out valleys and shape landscapes through the process of erosion.

Front

What is the difference between erosion and weathering?

Back

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

Front

What is an island formed by volcanic activity called?

Back

An island formed by volcanic activity is often referred to as a volcanic island.

Front

What happens during the process of weathering?

Back

During weathering, rocks are broken down into smaller pieces due to physical or chemical processes.
