Rock Types Igneous Rocks – formed from the solidification of a molten liquid when it cools Sedimentary Rocks – formed from consolidated sediments, cementation, or precipitated from solutions Metamorphic Rocks – sedimentary or igneous rocks changed by heat, pressure, or impact The key factors in determining rock type is texture and composition.

Igneous Rocks Igneous is derived from the Latin term ignis meaning fire. Igneous rocks are formed from the solidification and crystallization of a cooling magma. This is a exothermic (cooling) process from liquid to solid-state. Igneous rocks characteristics are controlled by: Rate of cooling; Magma geochemistry (controls mineralology); and Texture (size, shape, and arrangement of mineral grains).
