Weathering and Wetlands Review - 7th Period

Front

What is weathering?

Back

Weathering is the breaking down of rocks over a long period of time.

Front

What is the force behind weathering, erosion, and deposition?

Back

The force behind weathering, erosion, and deposition is gravity.

Front

What is an aquifer?

Back

An aquifer is an area of permeable sediment or rock that holds a significant amount of water.

Front

What happens when water no longer fills the pores in an aquifer?

Back

When water no longer fills the pores in an aquifer, the land sinks, and this is called a sinkhole.

Front

What is porosity?

Back

Porosity is a measure of a rock's ability to hold water.

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.

Front

What is deposition?

Back

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

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks, while erosion is the movement of those broken-down materials.

Front

What role does the sun play in weathering?

Back

The sun provides energy that drives weathering processes, such as temperature changes that cause rocks to expand and contract.

Front

What is permeability?

Back

Permeability is the ability of a material to allow fluids to pass through it.
