Front

What is a mineral?

Back

A mineral is a naturally occurring, inorganic solid with a definite chemical composition and crystalline structure.

Front

How can minerals be identified?

Back

Minerals can be identified based on their physical properties such as color, luster, hardness, and cleavage.

Front

What is the difference between rocks and minerals?

Back

Rocks are made up of one or more minerals, while minerals are not made up of rocks.

Front

What is luster in minerals?

Back

Luster refers to how light reflects off the surface of a mineral, indicating whether it is metallic or nonmetallic.

Back

A metallic mineral has a shiny appearance and reflects light like metal.

Front

What is the role of minerals in rocks?

Back

Minerals are the building blocks of rocks, providing structure and composition.

Front

What is cleavage in minerals?

Back

Cleavage is the tendency of a mineral to break along flat surfaces.

Front

What is hardness in minerals?

Back

Hardness is a measure of a mineral's resistance to scratching, often measured on the Mohs scale.

Front

What is the Mohs scale?

Back

The Mohs scale is a scale from 1 to 10 used to rank the hardness of minerals.
