Types of Rocks | Geology Page

Geologists classify rocks into three main groups: igneous rock, sedimentary rock, and metamorphic rock. Metamorphic Rock is formed by heat and pressure from other rocks. Depending on how the rock formed, rocks can be igneous, sedimentary, or metamorphic.

Igneous rocks are formed from the solidification of molten rock material. There are two basic types. Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form.

Pictures and Descriptions of Igneous Rock Types

Igneous rocks are those that form via the process of melting and cooling. If they erupt from volcanoes onto the surface as lava, they are called extrusive rocks.By contrast, Intrusive rocks are formed from magma that cools underground. If the intrusive rock cooled underground but near the surface, it is called subvolcanic or hypabyssal, and often has visible, but tiny mineral grains.Rock types in the UK - igneous, sedimentary and,,Rocks can be classified in to three main groups - igneous, sedimentary and metamorphic.
