Discuss the three different types of rocks ie igneous, sedimentary and metamorphic rocks in brief
Answers
Answer:
igneous rock = Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. 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.
sedimentary rocks = Sedimentary rocks are types of rock that are formed by 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.
metamorphic rock = Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change. The protolith may be a sedimentary,
