Sedimentary Rocks Pre-Flashcard

Front

What is sedimentary rock?

Back

Sedimentary rock is a type of rock formed from the accumulation and compaction of mineral and organic particles over time.

Front

What is the sedimentary rock cycle?

Back

The sedimentary rock cycle is the process through which sedimentary rocks are formed, broken down, and reformed, involving 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 by which sediments are pressed together under pressure, reducing their volume and leading to the formation of sedimentary rock.

Front

What are fossils?

Back

Fossils are the preserved remains or traces of ancient organisms found in sedimentary rocks, providing evidence of past life.

Front

How do sedimentary rocks show evidence of past environments?

Back

Sedimentary rocks often have layers that indicate different conditions over time, such as changes in water levels or climate.

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 a common example of sedimentary rock?

Back

Common examples of sedimentary rock include sandstone, limestone, and shale.
