California's Geology

California's remarkable geology is the result of volcanic and tectonic activity. Its majestic mountains were shaped by glaciers during the ice ages as well as by wind and rain. The scenic coastline of California is continually shaped by the pounding waves of the Pacific Ocean. California has a wealth of mineral resources, including the rich soil of the Central Valley, the gold of the Sierra, and oil off the coast and in various locations across the state. :)
