We rely on the Earth for valuable resources like soil, water, metals, industrial minerals, and energy, and we need to know how to acquire and harness these resources in a sustainable manner. By researching rocks and the fossils they contain, we may learn about the evolution of our environment and the life that exists within it. The production of rock, mountains, volcanoes, and earthquakes is influenced by plate tectonics. All of these things, as well as the mechanisms that created the Earth and continue to drive plate tectonics, can be learned through studying the Earth's innards.
