There are three types of rock
Sedimentary
Sedimentary rock is made when sediments are compacted together over a lot of time to create sedimentary. The One above is called, dolomite.
Metamorphic
Metamorphic rock formed when heat and pressure are added to igneous or sedamentiry. The one above is called, talc
Igneous
Igneous rock is formed when magma is cooled over time and becomes a hard igneous rock. The one above is called, coal
Dolomite
Compact limestone consisting of aragonite and calcite is compacted together using a lot of force over millions of years. It is mainly found in the U.S, Canada, Spain, Mexico, and Switterland. Dolomite is found in baby powder.
Talc
Dissolved magnesium runs through heated currents and mixes with silica then hardens. The Amin deposit of talc is found in the U.S. It is Lund in plastic paint, food, and rubber.
Coal
Over millions of years, dead trees plants, rocks, and animal corpses combine and are and it comes out as coal. Coal is found mainly in the U.S, China, Russia, India
