Science Chapter 10 C flashcard

Front

What are sedimentary rocks?

Back

Sedimentary rocks are types of rocks formed by the accumulation and compaction of mineral and organic particles. They are not the starting material for most versions of the rock cycle.

Front

What is a clastic rock?

Back

Clastic rocks are sedimentary rocks that are composed of fragments (clasts) of pre-existing rocks. Examples include conglomerate and breccia.

Front

Halite is a nonclastic rock that has a uniform milky, transparent appearance and is commonly known as rock salt.

Front

What are minerals?

Back

Minerals are naturally occurring inorganic substances that are the building blocks of rocks.

Front

What is the rock cycle?

Back

The rock cycle is a continuous process that describes the transformation of rocks through various geological processes, including weathering, erosion, sedimentation, and metamorphism.

Front

What is the difference between clastic and nonclastic rocks?

Back

Clastic rocks are made from fragments of other rocks, while nonclastic rocks are formed from chemical processes or biological activity.

Front

What is the significance of texture in rocks?

Back

Texture refers to the size, shape, and arrangement of grains in a rock, which can provide information about the rock's formation and history.

Front

What are the three main types of rocks?

Back

The three main types of rocks are igneous, sedimentary, and metamorphic.
