Sedimentary rocks

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of mineral and organic particles, often layered over time.

Front

What processes lead to the formation of sedimentary rocks?

Back

The formation of sedimentary rocks involves processes such as compaction and cementation of sediments.

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 cementation in sedimentary rock formation?

Back

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

Front

What characteristic do sedimentary rocks often have?

Back

Sedimentary rocks often have striped layers, which are formed by the deposition of different materials over time.

Front

What is the natural 'cement' that holds sediments together in sedimentary rocks?

Back

The natural 'cement' is made up of minerals that precipitate from water and bind the sediment particles.

Front

What type of rock is formed from layers of compressed sediments?

Back

Sedimentary rock is formed from layers of compressed sediments.

Front

What are clastic sedimentary rocks?

Back

Clastic sedimentary rocks are formed from fragments of other rocks and minerals that have been weathered and eroded.

Front

What are chemical sedimentary rocks?

Back

Chemical sedimentary rocks form when minerals precipitate from solution, often due to evaporation.

Front

What are organic sedimentary rocks?

Back

Organic sedimentary rocks are formed from the accumulation of plant or animal debris, such as coal.
