Sedimentary Rocks

Front

What is compaction in sedimentary rock formation?

Back

Compaction is the process where the weight of new sediment layers is deposited on top of older layers, causing the sediments to be squeezed together.

Front

What is NOT needed to make sedimentary rocks?

Back

Organic matter is not needed to make sedimentary rocks; the essential components are layers of sediment, compaction, and cementation.

Front

What is erosion?

Back

Erosion is the process by which water, wind, ice, or gravity removes pieces of rock from one location and transports them to another.

Front

What two processes turn solid rock into sandstone?

Back

Compaction and cementation are the two processes that transform solid rock into sandstone.

Front

What does putting pressure on sediments underground refer to?

Back

Putting pressure on sediments underground is called compaction.

Front

What are sedimentary rocks?

Back

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

Front

What is cementation in sedimentary rock formation?

Back

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

Front

What role does water play in sedimentary rock formation?

Back

Water helps transport sediments and can also facilitate the cementation process by dissolving minerals that bind sediments together.

Front

What is the difference between weathering and erosion?

Back

Weathering is the breaking down of rocks into smaller pieces, while erosion is the movement of those pieces from one place to another.

Front

What are the main types of sediment?

Back

The main types of sediment include clastic (rock fragments), chemical (precipitated minerals), and organic (remains of living organisms).
