Igneous rocks are one of the three main rock types, the are sedimentary and metamorphic. Igneous rocks are formed through the cooling and solidification of lava and magma.
Metamorphic rocks come 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 and/or chemical change.
Sedimentary Rocks are types of rocks that are formed by the deposition of material at Earth's surface and within bodies of water. Sedimentation is the collective name for processes that cause mineral and/or organic particles to settle and accumulate or minerals to precipitate from a solution.
