Unit 1 DA Review -Earth's Surface Changes: Landforms & Processes

Front

What is a constructive force?

Back

A constructive force is a natural process that builds up landforms, such as deposition of sediment or volcanic eruptions that create new land.

Front

What is a destructive force?

Back

A destructive force is a natural process that breaks down landforms, such as erosion caused by wind or water, or earthquakes that can destroy land.

Front

What is a sea arch?

Back

A sea arch is a natural rock formation created by the erosion of waves that carve out a section of a cliff, forming an arch shape.

Front

What is a river delta?

Back

A river delta is a landform created at the mouth of a river where sediment is deposited as the river meets a larger body of water.

Front

How do sand dunes form?

Back

Sand dunes form through the process of wind erosion that moves sand and deposits it in piles, creating a dune shape.

Front

What role does wind play in shaping landforms?

Back

Wind acts as a destructive force by eroding land and transporting sediment, but it can also be constructive by depositing sand to form features like dunes.

Front

What is deposition?

Back

Deposition is the process by which sediment is laid down in new locations, contributing to the formation of landforms like deltas and dunes.

Front

What is erosion?

Back

Erosion is the process by which natural forces like water, wind, or ice wear away rocks and soil, transporting the material to new locations.

Front

What is volcanic rock?

Back

Volcanic rock is formed when lava cools and solidifies after a volcanic eruption, contributing to the creation of new land.

Front

What is the difference between constructive and destructive processes?

Back

Constructive processes build up landforms, while destructive processes break down and erode existing landforms.
