Weathering, Erosion & Deposition

Front

What is weathering?

Back

Weathering is the process that breaks down rocks into smaller pieces through physical, chemical, or biological means.

Front

What is erosion?

Back

Erosion is the movement of sediment and soil from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process by which sediment settles out of the transporting medium (like water or wind) and accumulates in a new location.

Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks without changing their chemical composition, often caused by temperature changes, freeze-thaw cycles, or plant roots.

Front

What is chemical weathering?

Back

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

Front

What is oxidation in terms of weathering?

Back

Oxidation is a type of chemical weathering where minerals react with oxygen, often leading to rusting in iron-rich rocks.

Front

What role do glaciers play in erosion?

Back

Glaciers erode the landscape by scraping and carrying away rocks and sediment as they move.

Front

How does a river's speed affect sediment transport?

Back

A river's speed determines its ability to carry sediment; faster rivers can transport larger particles, while slower rivers drop sediment.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken pieces to new locations.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from the accumulation and compaction of sediment, often in layers.
