How do minerals form?

• Minerals form through crystallization from magma, precipitation from water, and biological processes.

• Minerals form through nuclear fusion

• Minerals form through evaporation from air

• Minerals form through combustion of organic matter

Explain the difference between cleavage and fracture in minerals.

• Cleavage is the way a mineral breaks with irregular surfaces, while fracture is the way a mineral breaks along flat surfaces.

• Cleavage is the way a mineral breaks into small pieces, while fracture is the way a mineral breaks into large pieces.

• Cleavage is the way a mineral breaks along flat surfaces, while fracture is the way a mineral breaks with irregular surfaces.

• Cleavage is the way a mineral breaks with smooth edges, while fracture is the way a mineral breaks with jagged edges.
