The Emergency Alert System (EAS) quiz assesses knowledge on various Earth science topics, including types of basaltic lava flows, ocean depths, wave behavior, faulting at mid-ocean ridges, atmospheric layers, and the formation of calcareous oozes. It is designed to enhance understanding of fundamental geological and oceanographic processes.
