Landforms (5.7B)

Front

What are landforms?

Back

Landforms are natural features of the Earth's surface, such as mountains, valleys, plateaus, and plains.

Front

What is weathering?

Back

Weathering is the process in which rocks are broken down into smaller pieces by natural forces like water, ice, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of weathered rock and soil from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments are dropped off in a new location, often forming features like deltas and sand dunes.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks into smaller pieces, while erosion moves those pieces to a different location.

Front

What is a delta?

Back

A delta is a landform created by the deposition of sediment at the mouth of a river, where it meets a body of water.

Front

What causes rapid changes to the Earth's surface?

Back

Rapid changes can be caused by events like volcanic eruptions, earthquakes, and landslides.

Front

What is the role of water in weathering?

Back

Water can enter cracks in rocks, freeze, and expand, causing the rock to break apart over time.

Front

What is a glacier?

Back

A glacier is a large mass of ice that moves slowly over land, shaping the landscape through erosion and deposition.

Front

What is the process of compaction?

Back

Compaction is the process where sediments are pressed together under pressure, often leading to the formation of sedimentary rock.
