Discuss the occurrence of a mineral resource. Relate it to the rock cycle and plate tectonics.   Mineral Resources: Rock Cycle and Plate Tectonics: Answer: Rock Cycle involves a geologic processes that plays a very important role in the accumulation and  concentration of valuable elements/minerals. Plate tectonics is geologic theory that explains why the Earth's crust is broken into a dozen or more plates of different sizes that  move relative to one another (lithosphere). These plates are moving slowly on top of a hot  and more mobile material called the asthenosphere. The diagram below shows the different  mineral deposits that usually occur in different tectonic environments.
