Plate Tectonics Vocabulary Flashcard

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed by the deposition, compaction, and cementation of sediments.

Front

How are sedimentary rocks formed?

Back

Sedimentary rocks are formed through the processes of deposition, compaction, and cementation of sediments.

Front

What is erosion?

Back

Erosion is the process of moving sediment from one place to another, often caused by water, wind, or ice.

Front

Give an example of erosion.

Back

Muddy water being carried away by a fast-moving river is an example of erosion.

Front

What is deposition?

Back

Deposition is the process by which sediments settle out of a transporting medium, such as water or air.

Front

What is bedrock?

Back

Bedrock is the solid rock layer beneath the soil and loose material, found everywhere on Earth.

Front

What is the difference between soil and bedrock?

Back

Soil is a layer of organic and inorganic material that supports plant life, while bedrock is the solid rock layer beneath it.

Front

What is the role of compaction in sedimentary rock formation?

Back

Compaction reduces the volume of sediments by squeezing them together, which helps in the formation of sedimentary rocks.

Front

What is cementation in geology?

Back

Cementation is the process where dissolved minerals precipitate and bind sediment particles together, forming solid rock.

Front

What is the main cause of erosion?

Back

The main causes of erosion are natural forces such as water, wind, and ice.
