Introduction 

Igneous rocks are rocks that solidify from molten material (magma). Cooling of the magma can occur beneath the surface (plutonic) or on the surface (volcanic). Igneous rocks can be identified by the determination of the composition and texture of the rock. Once these two characteristics have been identified, the Igneous Rock Identification chart is used to identify the rock name.

The purpose of this quiz is for you to practice identifying igneous rocks using their texture and composition
