How might rocks differ from each other?

Two igneous rocks are granite and basalt.

One type forms on Earth’s surface and the other forms below Earth’s surface.

The slower the rock cools and hardens, the larger its mineral grains will be.

the continuous process of volcanoes erupting

the continuous process of change in which rocks are created, destroyed, and recreated

the continuous process of sedimentary rock changing to become igneous rock

the continuous process of mineral grains making rocks smooth and shiny
