Sedimentary rock is a type of rock formed by the accumulation and compaction of sediments.

Front

What is erosion?

Back

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

Front

What is cementation?

Back

Cementation is the process in which dissolved minerals crystallize and glue particles of sediment together.

Front

What are sediments?

Back

Sediments are small pieces of rock, minerals, or organic material that have been broken down by weathering and erosion.

Front

How are sedimentary rocks formed?

Back

Sedimentary rocks are formed when sediments are pressed together and cemented over time.

Front

What role does time play in the formation of sedimentary rocks?

Back

It takes a long time for sedimentary rocks to form, often thousands to millions of years.

Front

What is the difference between sedimentary rocks and igneous rocks?

Back

Sedimentary rocks are formed from sediments, while igneous rocks are formed from cooled lava or magma.

Front

Can sedimentary rocks contain fossils?

Back

Yes, sedimentary rocks can contain fossils, which are the remains of ancient plants and animals.

Front

What is compaction in the context of sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure, reducing their volume.

Front

What is the significance of sedimentary rocks?

Back

Sedimentary rocks are important for understanding Earth's history, including past environments and life forms.
