Sedimentary Rock and Fossil Fuels Review

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What processes lead to the formation of sedimentary rock?

Back

The formation of sedimentary rock involves Weathering, Erosion, Deposition, Compaction, Cementation, Heat, and Pressure.

Front

What is weathering?

Back

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

Front

What is erosion?

Back

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

Front

What is deposition?

Back

Deposition is the process where sediments settle out of the transporting medium (like water or wind) and accumulate in a new location.

Front

What is compaction?

Back

Compaction is the process where sediments are pressed together under the weight of overlying materials, reducing their volume.

Front

What is cementation?

Back

Cementation is the process where dissolved minerals precipitate from water and fill the spaces between sediments, binding them together.

Front

What is the role of heat and pressure in sedimentary rock formation?

Back

Heat and pressure can transform sediments into sedimentary rock by causing chemical changes and further compaction.

Front

What is coal?

Back

Coal is a type of fossil fuel formed from decaying plants that have been buried under sedimentary rock.

Front

What is a fossil fuel?

Back

Fossil fuels are natural substances formed from the remains of ancient organisms, including coal, oil, and natural gas.
