What type of rock texture results when extreme pressure causes minerals in metamorphic rock to realign, or when minerals separate out into dark and light bands?

• felsic

• foliated

• mafic

• nonfoliated

Which statement describes the classification of water as a mineral?

• It is a mineral as a solid, a liquid, and a gas because it exists in all three states in nature.

• It is a mineral in nature only as a gas because it can condense back to a liquid at temperatures found on Earth.

• It is a mineral in nature only as a liquid because its high polarity allows many substances to dissolve in it.

• It is a mineral in nature only as a solid because it has a definite crystalline structure.
