1st Semester Interim Review (Rocks & Minerals & WEDS)

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, and then transported and deposited in other locations.

Front

What is deposition?

Back

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

Front

What force causes landslides?

Back

Gravity is the force responsible for erosion and deposition in landslides.

Front

What is mechanical weathering?

Back

Mechanical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.

Front

What is chemical weathering?

Back

Chemical weathering is the process that alters the chemical composition of rocks, often leading to their breakdown.

Front

What are the two main factors that determine the rate of weathering?

Back

The two main factors are the type of rock and climate.

Front

What is acid rain?

Back

Acid rain is precipitation that has a lower pH than normal, often caused by pollutants in the atmosphere, and can lead to the deterioration of buildings and natural features.

Front

What is a landslide?

Back

A landslide is a type of mass movement where a large amount of earth material moves down a slope due to gravity.

Front

What is a mudflow?

Back

A mudflow is a rapid flow of water-saturated soil and debris down a slope, often triggered by heavy rainfall.

Front

What is a slump?

Back

A slump is a type of mass movement where a section of land shifts downward along a curved surface.
