Weathering, Erosion, & Deposition

Front

What are the three elements needed to produce a sand dune?

Back

1. Abundant loose sand 2. Wind source 3. An object (such as a boulder, tree, or shrub) that obstructs the wind force and causes the sand to pile up in drifts.

Front

What happens to rocks in a river over time?

Back

The movement of water in a river causes the rocks to become smaller and smoother.

Front

What is weathering?

Back

Weathering happens when rocks on Earth's surface break apart or change without moving anywhere.

Front

How does a steep incline affect erosion?

Back

A steep incline results in more erosion.

Front

What is an example of physical weathering?

Back

Physical weathering involves the breaking down of rocks without changing their chemical composition.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by wind or water flow.

Front

What is deposition?

Back

Deposition is the process where materials are laid down or deposited after being transported by wind, water, or ice.

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 materials.

Front

What role does wind play in shaping landscapes?

Back

Wind can cause erosion by transporting sand and other materials, leading to the formation of features like sand dunes.

Front

What is chemical weathering?

Back

Chemical weathering involves the chemical alteration of minerals in rocks, often due to reactions with water or acids.
