What is a mineral and what are the five criteria for classification?1 / 11

A mineral is a naturally occurring, inorganic, solid substance with a definite chemical composition and an ordered crystalline structure. The five criteria: (1) Naturally occurring — formed by geological processes. (2) Inorganic — not produced by living organisms. (3) Solid — crystalline at normal conditions. (4) Definite chemical composition — can be expressed by a formula (e.g. quartz: SiO₂). (5) Ordered internal structure — atoms arranged in a repeating lattice.

What is a tectonic plate boundary?1 / 8

A tectonic plate boundary is the edge where two of Earth's rigid crustal plates meet. Because the plates are constantly moving — colliding, pulling apart, or sliding past each other — boundaries are where most of the planet's earthquake and volcanic activity happens.
