The Rock cycle is familiar territory to those that studied the Water cycle.
Like the Water on Earth, the rocks beneath our feet were here long before us and have been undergoing change since their creation.
Those same rocks are also made from materials that are constantly reshaped and reused over and over and over again. We will never gain MORE rocks, nor will we ever lose any. They cycle.
