Answer 2

Igneous rocks which formed by the crystallization of magma at the surface of the Earth called extrusive rocks. They are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.

So a common characteristic would be crystallization.
