Weathering, Erosion, Deposition and Landforms

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces by natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which weathered rock and soil are moved from one place to another, often by water, wind, or ice.

Front

What is deposition?

Back

The process where sediments, soil, and rocks are added to a landform or land mass, often occurring after erosion.

Front

What is physical weathering?

Back

The breaking down of rocks without changing their chemical composition, often caused by temperature changes, freezing, and thawing.

Front

What is chemical weathering?

Back

The process that breaks down rocks through chemical changes, such as acid rain reacting with minerals.

Front

What is an island?

Back

A body of land completely surrounded by water.

Front

What is a peninsula?

Back

A piece of land that is surrounded by water on three sides but connected to the mainland.

Front

What is frost wedging?

Back

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

Front

What is the role of glaciers in deposition?

Back

Glaciers can carry rocks and sediments and deposit them in new locations when they melt.

Front

What is oxidation in weathering?

Back

A chemical weathering process where oxygen reacts with minerals in rocks, often leading to rust.
