Unit 3 Test Review

Front

What is a bioclastic sedimentary rock?

Back

A bioclastic sedimentary rock is formed from the accumulation of biological debris, such as plant and animal remains. An example is bituminous coal.

Front

In which type of rock are fossils primarily found?

Back

Fossils are primarily found in sedimentary rocks.

Front

What is Soil Horizon B also known as?

Back

Soil Horizon B is also known as Subsoil.

Front

What is the process called when rocks break into smaller pieces due to exposure to natural elements?

Back

The process is called weathering.

Front

What happens during erosion?

Back

During erosion, wind or water picks up smaller particles and transports them, leaving behind larger rocks.

Front

Define sedimentary rock.

Back

Sedimentary rock is formed from the accumulation and compaction of mineral and organic particles.

Front

What is the difference between foliated and nonfoliated metamorphic rocks?

Back

Foliated metamorphic rocks have a layered or banded appearance due to the alignment of minerals, while nonfoliated rocks do not have this structure.

Front

What is the role of weathering in the rock cycle?

Back

Weathering breaks down rocks into smaller particles, which can then be transported and deposited to form sedimentary rocks.

Front

What is the significance of soil horizon layers?

Back

Soil horizon layers indicate the different stages of soil development and composition, affecting plant growth and ecosystem health.

Front

What is deposition in the context of sedimentary processes?

Back

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