Unit 2 Lesson 1 Review: Erosion/deposition by water

Front

What is erosion?

Back

Erosion is the process by which weathered rock and soil are removed from one location and transported to another by natural forces such as water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediments, soil, and rocks are added to a landform or land mass, often occurring when the transporting medium loses energy.

Front

What factors affect runoff?

Back

Factors affecting runoff include vegetation, amount of rain, soil type, and land slope. Weathering does not affect runoff.

Front

Which type of rock erodes quicker: hard rock or soft rock?

Back

Soft rock erodes quicker than hard rock due to its less dense and more fragile structure.

Front

What is weathering?

Back

Weathering is the breakdown of rocks into smaller particles through physical, chemical, or biological processes.

Front

What is the difference between erosion and weathering?

Back

Weathering is the breakdown of rocks, while erosion is the movement of those weathered materials from one place to another.

Front

What role does vegetation play in erosion?

Back

Vegetation helps to reduce erosion by stabilizing the soil with roots and absorbing water, which decreases runoff.

Front

What is an example of deposition?

Back

An example of deposition is sand that is dropped on the beach by waves.

Front

How does water contribute to erosion?

Back

Water contributes to erosion by flowing over land, carrying away soil and rock particles, especially during heavy rainfall.

Front

What is the impact of heavy rainfall on runoff?

Back

Heavy rainfall increases runoff, leading to greater erosion and potential flooding.
