Unit 3 Earth Processes

Front

What is Erosion?

Back

Erosion is the process by which wind, water, ice, and gravity transport sediment from one location to another.

Front

What is Weathering?

Back

Weathering refers to the chemical and physical processes that break down rock at the Earth's surface.

Front

What is an Aquifer?

Back

An aquifer is an underground area that holds groundwater, similar to a sponge.

Front

What is Deposition?

Back

Deposition is the process where sediment is laid down in a new location after being transported.

Front

What is an Ecoregion?

Back

An ecoregion is a large area characterized by specific environmental conditions and communities of plants and animals.

Front

What is the Texas Hill Country?

Back

The Texas Hill Country, also known as the Edwards Plateau, features springs, stony hills, and steep canyons.

Front

What role does gravity play in erosion?

Back

Gravity helps to pull sediment downhill, contributing to the erosion process.

Front

What are the two main types of weathering?

Back

The two main types of weathering are physical weathering (breaking down rocks without changing their composition) and chemical weathering (breaking down rocks by changing their chemical composition).

Front

How does water contribute to erosion?

Back

Water can erode rocks and soil by flowing over them, carrying sediment away with its current.

Front

What is sediment?

Back

Sediment is small particles of rock, soil, and organic material that are transported by wind, water, or ice.
