Earth Science & Geology

Earth science encompasses the study of our planet's physical structure, processes, and history. Geology investigates rocks, minerals, and the processes of plate tectonics that drive earthquakes, volcanic eruptions, and mountain building. It also covers the rock cycle, glaciation, and the interpretation of fossil records. Meteorology studies the atmosphere and weather; oceanography examines the seas; and geophysics probes the deep interior of Earth. Together these disciplines reveal how our dynamic planet has changed over 4.5 billion years and continues to change today. This sub-category tests scientific knowledge of Earth's composition, geological history, natural hazards, and the powerful internal and external forces that constantly reshape the planet's surface and interior.
