Geology Pt. 1 CIA Review

Front

What are the properties of a mineral?

Back

Minerals have properties such as hardness, luster, color, and being solid and inorganic.

Front

What is the rock cycle?

Back

The rock cycle is a long process through which rocks change from one type to another, including igneous, sedimentary, and metamorphic rocks.

Front

Which layer of the Earth is the least dense?

Back

The crust is the least dense layer of the Earth.

Front

What is subduction?

Back

Subduction occurs when a less dense tectonic plate slides under a more dense plate.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where tectonic plates slide or move past each other.

Front

What is the definition of hardness in minerals?

Back

Hardness is a measure of how resistant a mineral is to being scratched.

Front

What is luster in minerals?

Back

Luster refers to how a mineral reflects light, which can be described as metallic, glassy, or dull.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is continental drift?

Back

Continental drift is the theory that continents have moved over geological time and were once joined together.

Front

What is the difference between igneous, sedimentary, and metamorphic rocks?

Back

Igneous rocks form from cooled magma, sedimentary rocks form from compressed sediments, and metamorphic rocks form from existing rocks that change due to heat and pressure.
