But can someone explain to me what are sedimentary, metamorphic and magmatic rock

answer: sedimentary, magmatic and metamorphic rocks

explanation: sedimentary rocks are types of rock which are formed as a result of the accumulation or deposition of small particles and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the earth's surface. sedimentation is the collective name for processes that cause these particles to settle in place. the particles that form a sedimentary rock are called sediment, and may also be composed of geological detritus (minerals) or biological detritus (organic matter).

metamorphic rocks arise from the transformation of existing rock types, in a process termed metamorphism, which means "change in form. the original rock called protolith is subjected to heat (temperatures greater than 150 to 200 °c) and pressure (100 megapascals (1,000 bar) or more), leads to a profound physical or chemical change. the protolith may be a sedimentary, igneous, or existing metamorphic rock. metamorphic rocks make up a large part of the earth's crust and form 12% of the earth's land surface. they are classified by texture and by chemical and mineral assemblage (metamorphic facies).

magmatic or igneous rock is formed through the cooling and solidification of magma or lava. the magma can be derived from partial melts of existing rocks in either a planet's mantle or crust, the melting is caused by one or more of three processes: an increase in temperature, a decrease in pressure, or a change in composition. solidification into rock takes place either below the surface as intrusive rocks or on the surface as extrusive rocks. igneous rock may form with crystallization to form granular, crystalline rocks, or without crystallization to form natural glasses..igneous rocks take place in a wide range of geological settings: shields, platforms, orogens, basins, large igneous provinces, extended crust and oceanic crust.
