Detailed explanation-1: -Rock cycle is a continuous process through which old rocks are transformed into new ones. Igneous rocks are primary rocks, and other rocks form from these rocks. Igneous rocks can be changed into sedimentary or metamorphic rocks. The fragments derived out of igneous and metamorphic rocks form into sedimentary rocks.
Detailed explanation-2: -Metamorphic rocks are those rocks that have undergone changes in mineralogy, texture and/or chemical composition as a result of changes in temperature and pressure. The original rock may have been igneous, sedimentary or another metamorphic rock.
Detailed explanation-3: -Metamorphic rocks, meta-meaning change and –morphos meaning form, is one of the three rock categories in the rock cycle (see Chapter 1). Metamorphic rock material has been changed by temperature, pressure, and/or fluids. The rock cycle shows that both igneous and sedimentary rocks can become metamorphic rocks.
