Chap 5 and 6 Test

Front

What is Mechanical Weathering?

Back

Mechanical Weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition. An example is tree roots growing out of rocks.

Front

What is Chemical Weathering?

Back

Chemical Weathering is the process that causes exposed rock to undergo chemical decomposition, changing the chemical and mineral make-up of the rock.

Front

What is Erosion?

Back

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

Front

What is Deposition?

Back

Deposition is the process in which sediments, soil, and rocks are added to a landform or land mass, often after being transported by erosion.

Front

What type of rock is formed by Erosion and Deposition?

Back

Sedimentary rock is formed by the processes of erosion and deposition.

Front

What is Abrasion in the context of weathering?

Back

Abrasion is a type of mechanical weathering that occurs when rocks and sediments are worn away by friction and contact with other materials.

Front

What is Ice Wedging?

Back

Ice Wedging is a mechanical weathering process where water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.

Front

What is the role of Plant Takeover in weathering?

Back

Plant Takeover refers to the process where plant roots grow into cracks in rocks, contributing to mechanical weathering as they expand.

Front

What is the difference between Mechanical and Chemical Weathering?

Back

Mechanical Weathering breaks rocks into smaller pieces without changing their composition, while Chemical Weathering alters the chemical structure of the rocks.

Front

What are Hoodoos?

Back

Hoodoos are tall, thin spires of rock that have been formed by erosion, often found in places like Bryce Canyon.
