3 Types of Rock Formations Sciencing

The formation of rocks results in three general types of rock formations. Igneous rocks form from magma (intrusive igneous rocks) or lava (extrusive igneous rocks). Sedimentary rocks form from sediments worn away from other rocks. Metamorphic rocks occur when heat and/or pressure impact other rocks.
