Rocks and Minerals

There are three basic classes of rocks: igneous, metamorphic, and sedimentary. Igneous rocks are those that solidified from magma (molten rock). Metamorphic rocks are formed from pre-existing rocks in a solid state by heat, pressure, and/or chemical activity. Sedimentary rocks are made up of particles of sediment cemented together. In Arkansas, the overwhelming majority of surface and near Get price
