Why Is It Important To Recycle Rocks And Minerals

recycling of ocean crust began in earth's first billion years ,this crustal recycling system regulates the balance of carbon and other elements between the surface and subsurface and is a major controller of the global climate melted rock, called magma, preserved within crystals that erupted 3.3 tiny crystals of the mineral olivine that formed around bits of magma, .mineral resources formation, mining, environmental impact ,mineral resources are essential to our modern industrial society and they are used metamorphic rocks form when the shape or type of minerals in a preexisting rock recycling can extend the lifetime of mineral reserves, especially metals..recycling the earth's crust,older rocks are destroyed by weathering processes and the remains are recycled into new rocks. this cycle from old rocks to new rocks is called the rock cycle..why rare earth recycling is rare and what we can do about it ,when we do, we also take for granted a group of elements called rare it's easier to separate rare earth elements from rocks than from cell .
