  • Metamorphic Rocks | National Geographic Society

    10/10/2019· In the rock cycle, there are three different types of rocks: sedimentary, igneous, and metamorphic Sedimentary and igneous rocks began as something other than rock Sedimentary rocks were originally sediments, which were compacted under high pressure Igneous rocks formed when liquid magma or lava—magma that has emerged onto the surface of the Earth—cooled and hardened A metamorphic rock

  • Igneous rock Wikipedia

    Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphicIgneous 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 crustTypically, the melting is caused by one or more of
