igneous metamorphic sedimentary definition
Making the world better, one answer at a time. An igneous rock is a rock that started as molten magma then cooled and solidified either above,on,or below the surface. An sedimentary rock is a type of rock that is formed by sedimentation of material at the earths surface and within bodies of water.An metamorphic rock is the result of the transformation of an existing rock type, the protolith, in a process called metamorphism, which means ''change in form.he particles formed are then be redeposited to form new sedimentary rocks. To form an igneous rock out of a metamorphic rock you need have conditions in the Earth that will raise the temperature high enough to form a melt out of the rocks. This melt (magma) can then form new igneous rocks.
