Natural Hazards and the Geologic Cycles

geology

influences the type, location, and intensity of natural processes and hazards

tectonic cycle

creation, destruction, and movement of tectonic plates (driven by internal energy)

rock cycle

formation and transformation of igneous, sedimentary, and metamorphic rocks (internal energy, radioactive decay)

hydrologic cycle

movement of water on, above, and below the surface of the earth (external energy like the sun)

biogeochemical cycle

transfer of chemical elements through earth’s spheres (biosphere, atmosphere, hydrosphere, cryosphere, and geosphere)
