Introduction to Desert Geology
Far from being static, the geology of Earth is dynamic, in constant motion and change. The crust is a puzzle made up of tectonic plates, shifting against one another over a molten layer of magma. During the changing relationship of the plates, Earth’s crust has undergone compression and stretching, creating vast breaks in the surface known as faults. Periods of mountain building uplifted the great mountain chains of the world. Since the Precambrian Era, the Mojave Desert has experienced many different phases over almost incomprehensible time periods.
