Compare the texture of igneous rocks that crystallize deep inside Earth with those that crystallize on Earth's surface.
Igneous rocks that form underground have coarser texture with larger grains because they had longer to form; igneous rocks that form above ground have a finer texture because they formed quickly and the grains didn't have as much time to grow.

What is ... Sedimentary rocks can form from igneous rocks or metamorphic rocks that are exposed to weathering and erosion and then compaction and cementation. Igneous rocks form from the cooling of lava (on Earth's surface) or magma (in Earth's surface) or melting of metamorphic rocks that recrystallize. Metamorphic rocks can form from sedimentary and igneous rocks that are exposed to extreme heat and pressure.
