Weathering, Erosion, and Deposition

Front

What is weathering?

Back

The process of breaking down rocks and minerals into smaller pieces by physical, chemical, or biological means.

Front

What are the two main types of weathering?

Back

Mechanical (physical) weathering and chemical weathering.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another, often by water, wind, or ice.

Front

What is deposition?

Back

The process in which sediments, soil, and rocks are added to a landform or land mass.

Front

How does frost action contribute to weathering?

Back

Frost action causes rocks to break apart as water expands when it freezes, leading to mechanical weathering.

Front

What is a delta?

Back

A landform made of sediment that is deposited where a river flows into an ocean or lake.

Front

What is carbonation in the context of weathering?

Back

A chemical weathering process where carbon dioxide dissolves in water, forming carbonic acid, which can dissolve minerals.

Front

What is an example of mechanical weathering?

Back

Frost wedging, where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What role does water play in erosion?

Back

Water can carry away sediments and rocks, especially in fast-moving rivers, leading to erosion.

Front

What is oxidation in chemical weathering?

Back

A process where minerals react with oxygen, often leading to rusting in iron-rich rocks.
