Question

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

Explanation:

When lava cools at Earth's surface, it cools rapidly. Rapid - cooling does not allow enough time for large crystals to form, resulting in small crystals. Magnetic and hexagonal crystal formation are not directly related to surface - lava crystallization.

Answer:

B. small crystals
