Best Answer: Igneous rocks are made by: melting, cooling, crystallization and then destroyed by the way sedimentary rocks are made by: weathering, erosion/transport, deposition/precipitation, lithification and then destroyed by the way metamorphic rocks are made by: increased temperature, increased pressure, migrating fluids. read more
Sedimentary rock becomes smaller and smaller due to physical and chemical weathering. Metamorphism and melt would also create new material from sedimentary rock. read more
The Rock Cycle is Earth's great recycling process where igneous, metamorphic, and sedimentary rocks can all be derived from and form one another read more
