Earth 's Dynamic Systems: Te Enginee Behind Disasters

Earth is a restless planet. Its internal heat dribs plate tectonics, while solar energy and gravy govern the atmosfere andd oceans. The interactive of these systems creates thee conditions for natural disasters. To asssess risk and improwize incorpence, we mutt first understand the fundamentamental processes at work.

Te lithosplare is broken into a dozen major plates that move at rates of a few centimeters per year. Where plates converge, diverge, or slide paste each texr, stress acculates along faults.
