Sedimentary rocks

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of sediments, which can include minerals, organic matter, and fragments of other rocks.

Front

What characteristic do sedimentary rocks often have?

Back

Striped layers.

Front

What processes are involved in producing sediments?

Back

Weathering and Erosion.

Front

What are sediments?

Back

Sediments are small pieces of material, such as pebbles, sand, and fragments of other rocks, that are transported by wind, water, or ice.

Front

What is compaction in the context of sedimentary rocks?

Back

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

Front

What is the oldest layer in a sequence of sedimentary rock layers?

Back

The oldest layer is typically at the bottom of the sequence.

Front

What is the role of water in the formation of sedimentary rocks?

Back

Water helps transport sediments and can also aid in the compaction and cementation processes.

Front

What is cementation in sedimentary rock formation?

Back

Cementation is the process where dissolved minerals crystallize and bind sediment particles together.

Front

What are the two main types of weathering?

Back

Physical weathering and chemical weathering.

Front

What is physical weathering?

Back

Physical weathering is the breaking down of rocks into smaller pieces without changing their chemical composition.
