Explanation:

Igneous rocks are formed deep inside Earth’s crust (intrusive rocks) or at the surface (extrusive rocks). As molten rock (known as magma) below the surface cools, the liquid material begins to solidify into minerals of differing 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 gabbro.
