There are three major groups of rock: Igneous; Sedimentary; Metamorphic. They are all related through a continuous cycle called the rock cycle. Igneous rocks are created by melting and crystallization of molten material called magma. If the magma reaches the surface, the rocks are said to be extrusive. Volcanic lava flows are examples of extrusive igneous rocks.
As a result of these processes, three main types of rock occur: Igneous Rocks-produced by solidification of molten magma from the mantle. Magma that solidifies at the Earth's surface conceives extrusive or volcanic igneous rocks.When magma cools and solidifies beneath the surface of the Earth intrusive or plutonic igneous rocks are formed.Sedimentary Rocks-formed by burial, compression, and chemical modification of deposited weathered rock debris or sediments at the Earth's surface.he most well-known mineral of this group is halite (NaCl) or rock salt. Figure 10d-6: Halite or rock salt. The Oxides are a group of minerals that are compounds of one or more metallic elements combined with oxygen, water, or hydroxyl (OH).
