Why do minerals form crystals?

Answer: Atoms arrange in repeating patterns

Random chance arrangements — Wrong. Crystal formation isn't random—it follows specific atomic structures based on chemical bonding and energy minimization.

Atoms arrange in repeating patterns ✓ — Correct! When minerals solidify from liquid or gas, atoms arrange themselves in the most energy-efficient configuration—repeating geometric patterns. This creates crystal structures with flat faces and specific angles. Quartz always forms hexagons, halite (salt) forms cubes—predictable from atomic structure! It's chemistry creating geometry.

Magnetic forces align particles — Wrong. While some minerals are magnetic, crystal shapes are determined by chemical bonding geometry, not magnetic forces.
