Sedimentary Rock Test

Front

What is erosion?

Back

Erosion is the process by which running water, wind, or ice carry away bits of broken-up rock.

Front

What is the correct order for the construction of sedimentary rock?

Back

The correct order is weathering, erosion, deposition, lithification.

Front

What is organic matter?

Back

Organic matter refers to the waste and remains of plants and animals.

Front

What type of organic material does coal form from?

Back

Coal only forms from peat.

Front

What type of rock makes up most of the Earth's crust?

Back

Most of the Earth's crust is made up of igneous rock, but most rock at the surface is sedimentary.

Front

Define lithification.

Back

Lithification is the process of turning sediment into solid rock through compaction and cementation.

Front

What is sediment?

Back

Sediment is small, solid pieces of material that come from rocks or living things.

Front

Explain the process of deposition.

Back

Deposition is the process where sediment settles out of the transporting medium (like water or wind) and accumulates.

Front

What is the role of weathering in sedimentary rock formation?

Back

Weathering breaks down rocks into smaller particles, which are then transported and deposited to form sedimentary rock.

Front

What is cementation?

Back

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