Answer:

Igneous rocks are one of three main types of rocks (along with sedimentary and metamorphic), and they include both intrusive and extrusive rocks.

The igneous rocks are the rocks that are formed by the solidified process of the magma rocks. It is the result of the intrusive or the extrusive magma or the fire. It is wholly related to the fire or the lava.

The igneous rocks are classified into:

  • Chemical/mineral composition

         felsic

         intermediate

         mafic

        ultramafic

        texture or grain size

  • intrusive rocks

  • extrusive rocks

  • Volcanic rocks

These are the rocks that are especially of the quality of the felsic or the intermediate. These all depend on the texture and the quality of the rocks.
