How would a geologist identify where an igneous rock was formed?

5 0

Igneous rocks form when magma from inside the Earth moves toward the surface or is forced above the Earth's surface as lava and ash by a volcano.
Many igneous rocks can be identified by the position of their minerals. The minerals usually fit together like pieces of a jigsaw puzzle.
