• solid, inorganic substance with a fixed chemical composition and crystal system.

• solid,naturally occurring, inorganic substance with a fixed chemical composition and crystal system.

• inorganic substance with a fixed chemical composition and crystal system.

What does it mean to say that a mineral is inorganic?

• It is made from living things.

• It can not be made from living things.

• It is made from things.

• It can be made from anything.

Name 8 properties that can be used to identify minerals.

• Color and texture

• Color, streak, luster, density, hardness, crystal system, cleavage & fracture, special properties

• Color, streak, luster, hardness, crystal system, cleavage & fracture

• Color, streak, luster, density, hardness, crystal system, cleavage & fracture,

What is the difference between fracture and cleavage?

• Cleavage describes how a mineral breaks apart in an irregular way. Fracture describes how a mineral breaks apart along flat surfaces.

• Fracture describes how a mineral breaks in an irregular way. Cleavage describes how a mineral breaks apart along bumpy surfaces.

• Fracture describes how a mineral breaks apart along flat surfaces. Cleavage describes how a mineral breaks in an irregular way.

• There is no difference.

What are intrusive igneous rocks/how are they formed

• They are formed when magma hardened on Earth's surface.

• They are formed when lava cools underneath Earth's surface.

• They formed when magma hardened beneath Earth’s surface.

• They are formed when lava cools on Earth's surface.
