Explanation:

Metamorphic rocks are not the changed form of igneous rocks only but they are formed from sedimentary rocks also. Metamorphic rocks came into being when there is a change in the physical and chemical properties of igneous and sedimentary rocks under the influence of heat and pressure. The process is known as metamorphism.
