Weathering, Erosion, Deposition and Sedimentary Rocks

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces through natural forces such as wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by water, wind, or ice.

Front

What is deposition?

Back

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

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of mineral and organic particles, often found in layers.

Front

How do strong winds contribute to the formation of sand dunes?

Back

Strong winds can move sand particles from one place to another, piling them up to form sand dunes.

Front

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, leading to the formation of sedimentary rocks.

Front

What role do decomposed plants and animals play in the formation of oil and natural gas?

Back

Decomposed plants and animals, over millions of years, can transform into oil and natural gas when buried under layers of sediment.

Front

What is a delta?

Back

A delta is a landform created at the mouth of a river where it meets a body of water, formed by the deposition of sediment as the river slows down.

Front

Why might a fence be built between a sand dune and a road?

Back

A fence may be built to stop sand from sliding or blowing onto the road and covering it.

Front

What is the difference between weathering and erosion?

Back

Weathering breaks down rocks in place, while erosion involves the movement of those broken materials to a different location.
