How is slate rock formed?
Slate is a type of metamorphic rock, created from sedimentary rocks. Slate can be found in a number of places throughout the world.SlateSlate breaks into thin sheets in a process called cleavage. Slate rocks are used in a number of ways, including construction.Rock CycleThe rock cycle consists of three main stages. Igneous rocks are formed from magma or lava. Sedimentary rocks are formed from the sediments like silt, sand and pebbles that result from erosion. Metamorphic rocks form when sedimentary rocks are subject to a great deal of heat and pressure.Metamorphic RocksThere are different kinds of metamorphic rocks. Slate is created by two types of sedimentary rock, shale and mudstone, that are subjected to pressure and heat.FormationSlate is formed when shale or mudstone undergo metamorphosis. This process is slow and requires that the shale or mudstone be placed under a great deal of pressure. The pressure causes the grains in the rock to align in well-defined patterns, which result
