Unit 4: Changes in the Earth's Surface

Front

What is a sea arch?

Back

A sea arch is a natural rock formation that is formed by the erosion of waves on the coastline, creating an arch shape.

Front

How is a sea arch formed?

Back

Waves are destructive forces that over time can wear away at the earth’s coast and change its shape.

Front

What is a mountain?

Back

A mountain is a large landform that rises prominently above its surroundings, typically formed by tectonic plates pushing together.

Front

How is a mountain created?

Back

A mountain is created when tectonic plates push together slowly over time, showing a constructive process.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down materials, while erosion moves materials from one place to another.

Front

What are constructive processes?

Back

Constructive processes are natural events that build up the Earth's surface, such as volcanic eruptions and sediment deposition.

Front

What are destructive processes?

Back

Destructive processes are natural events that wear down or remove materials from the Earth's surface, such as erosion and weathering.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural forces such as wind or water.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through natural forces.

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.
