Unit 4 Study Guide

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's crust that move and interact with each other, causing geological events like earthquakes and the formation of mountains.

Front

What is the process of mountain formation called?

Back

The process of mountain formation is called orogeny, which occurs when tectonic plates collide.

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, water, and ice.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass.

Front

How does wind cause erosion?

Back

Wind causes erosion by moving sediment across the land; faster winds can carry more sediment.

Front

What are constructive forces?

Back

Constructive forces are natural processes that build up landforms, such as volcanic eruptions that create new land.

Front

What are destructive forces?

Back

Destructive forces are natural processes that break down landforms, such as erosion and volcanic eruptions.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through physical, chemical, or biological means.

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 is the role of water in erosion?

Back

Water causes erosion by carrying away sediment and can create features like gullies and riverbanks over time.
