Sedimentary Rock POST-TEST

Front

What is organic limestone?

Back

A type of sedimentary rock that is formed from the accumulation of organic materials, such as shells and coral.

Front

Why are most fossils found in sedimentary rocks?

Back

Because fossils form from the remains of organisms that are buried and preserved in sediment, which is primarily found in sedimentary rocks.

Front

What is the correct order of physical formation for clastic sedimentary rocks?

Back

Weathering, erosion, deposition, sedimentation, compaction, cementation.

Front

Which layer of sedimentary rock is the oldest?

Back

The bottom layer (Layer A) is the oldest due to the principle of superposition.

Front

What is halite?

Back

Halite is a chemical sedimentary rock commonly known as rock salt, formed from the evaporation of water.

Front

What are sedimentary rocks?

Back

Rocks formed by the accumulation and compaction of mineral and organic particles.

Front

What is weathering?

Back

The process of breaking down rocks into smaller pieces through natural forces like wind, water, and temperature changes.

Front

What is erosion?

Back

The process by which soil and rock are removed from one location and transported to another by natural forces.

Front

What is deposition?

Back

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

Front

What is compaction in sedimentary rock formation?

Back

The process where sediments are pressed together under pressure, reducing their volume.
