Explanation: Igneous rocks are formed Deep inside Earth's crust or at the surface. As molten Rock below the surface cools, the liquid material begins to solidify into minerals of different sizes and compositions. generally the longer the cooling time the larger the mineral crystals can grow. trapped deep in the earth, Magma is allowed to cool slowly. examples of intrusive rocks are granite and gebbro.
