Minerals and the Rock Cycle

A naturally occurring, inorganic solid with an orderly internal structure and a definite chemical composition.

• Rock

• Element

• Mineral

• Atom

All of the following apply to the formation of minerals EXCEPT.

• Crystallization from magma

• Precipitation

• Changes in pressure and temperature

• Weathering and erosion

• Formation from hydrothermal solutions

Color is not a useful identification property because

• some minerals are colorless.

• the same mineral can be different colors.

• different minerals can be different colors.

• some minerals are single elements.

Minerals that form from magma form as a result of

• crystallization

• evaporation

• precipitation

• condensation

A mineral's streak is

• the way the mineral reacts to hydrochloric acid.

• the resistance to being scratched.

• the color of the mineral in powdered form.

• the way in which a mineral reflects light.

The Mohs scale is a scale that is used to determine a mineral's

• luster

• cleavage

• hardness

• streak

The most common minerals on Earth

• Carbonates

• Silicates

• Oxides

• Halides

Silicates contain

• sulfur

• silicon and oxygen

• carbon

• halogens

Sulfates and sulfides contain

• sulfur

• silicon and oxygen

• carbon

• halogens

Oxides contain

• sulfur

• silicon and oxygen

• oxygen plus one other element

• halogens plus one other element
