Sedimentary Rocks Pre-Flashcard

Front

What are sedimentary rocks?

Back

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

Front

How do sedimentary rocks provide evidence of past environments?

Back

Sedimentary rocks often have layers that show different conditions over time, indicating changes in the environment.

Front

What is the sedimentary rock cycle?

Back

The sedimentary rock cycle includes processes such as weathering, erosion, deposition, and compaction.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks into smaller pieces due to environmental factors like wind, water, and temperature changes.

Front

What is erosion?

Back

Erosion is the movement of sediment from one location to another, often caused by water, wind, or ice.

Front

What is deposition?

Back

Deposition is the process where sediments settle out of the transporting medium (like water or wind) and accumulate in a new location.

Front

What is compaction?

Back

Compaction is the process where sediments are pressed together under pressure, reducing the space between them.

Front

What is the difference between igneous and sedimentary rocks?

Back

Igneous rocks are formed from the cooling and solidification of molten rock, while sedimentary rocks are formed from the accumulation of sediments.

Front

What is an example of a sedimentary rock?

Back

An example of a sedimentary rock is sandstone, which is formed from sand particles.

Front

What role do fossils play in sedimentary rocks?

Back

Fossils are often found in sedimentary rocks, providing evidence of past life and environments.
