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.

How are fossil fuels formed?

Back

Fossil fuels are formed from the remains of decaying plants and animals that are buried under layers of sediment and subjected to heat and pressure over millions of years.

What is peat?

Back

Peat is an accumulation of partially decayed organic matter, primarily from plants, that can eventually transform into coal under the right conditions.

What is compaction in geology?

Back

Compaction is the process by which 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 sediment grains, binding them together to form rock.

Front

What role does water play in sedimentary rock formation?

Back

Water helps transport sediments and, through its weight, contributes to the compaction of sediments into solid rock.

Front

What is erosion?

Back

Erosion is the process by which rocks and soil are worn away and transported by natural forces such as wind, water, or ice.

Front

What is weathering?

Back

Weathering is the breaking down of rocks into smaller pieces by physical, chemical, or biological processes.

Front

What is the difference between physical and chemical weathering?

Back

Physical weathering breaks rocks into smaller pieces without changing their chemical composition, while chemical weathering alters the minerals within the rocks.

Front

What is the significance of layers in sedimentary rocks?

Back

Layers in sedimentary rocks indicate different periods of deposition and can provide information about the Earth's history and past environments.
