Answer: Metamorphic rocks
Notes: The type of rocks that are formed from existing rocks through recrystallization are known as metamorphic rocks. The word metamorphic means ‘change of form’. Igneous rocks are formed by the solidification of hot molten material called magma or lava. The word igneous is derived from the Latin word ‘ignis’ meaning fire. Sedimentary rocks are formed by the deposition of sediments of rocks by exogenous forces. The word ‘sedimentary’ is derived from the Latin word sedimentum, which means settling.
