This paper was written to inform students with little to no knowledge about earth's
natural cycle of volcanic activity with emphasis on magma's chemical composition from a basic
chemical perspective. The knowledge acquired to form this paper was obtained
Magma is a molten material with a mixture of liquid rock, crystals, and dissolved gases
beneath the earth's crust. Igneous rocks form through the crystallization of magma at different
temperatures. Occasionally magma will work its way to the surface of ea
