Question

which characteristic is expected of a mineral that crystallizes from lava at earths surface?
○ large crystals
○ small crystals
○ magnetic crystals
○ hexagonal crystals

Explanation:

Lava cools very quickly when it reaches Earth's surface. Rapid cooling gives mineral atoms little time to arrange into large, well-formed structures, resulting in small crystals. Magnetic properties and hexagonal crystal shape are not universal traits for surface-cooled lava minerals, and large crystals form from slow, underground cooling of magma.

Answer:

small crystals
