Chapter 8 - Erosion and Deposition

Front

What is erosion?

Back

Erosion is the process of transporting broken down rock material from one place to another, often by wind, water, or ice.

Front

What is deposition?

Back

Deposition is the process where eroded materials are dropped or settled in a new location, forming layers of sediment.

Front

What is weathering?

Back

Weathering is the breaking down of rocks and minerals into smaller pieces due to natural forces like wind, water, and temperature changes.

Front

What is a landslide?

Back

A landslide is the sudden and fast movement of a large amount of earth material down a slope, often triggered by heavy rain or earthquakes.

Front

What is the difference between slump and creep?

Back

Slump is a type of mass movement where a section of land moves down a slope in a rotational manner, while creep is a slow, gradual movement of soil down a slope.

Front

What causes dunes to form?

Back

Dunes are formed by the wind blowing sand into mounds or hills, often found in deserts or along coastlines.

Front

What is a longshore current?

Back

A longshore current is a water current that moves parallel to the shoreline, caused by waves hitting the beach at an angle.

Front

What is the role of water in erosion?

Back

Water can erode rocks and soil by flowing over them, carrying away particles and shaping the landscape.

Front

What are sediment layers?

Back

Sediment layers are deposits of sand, silt, clay, and other materials that accumulate over time, often found at the bottom of lakes or rivers.

Front

How does wind contribute to erosion?

Back

Wind can pick up and carry small particles of sand and dust, eroding surfaces and shaping landforms like dunes.
