Interactive multiple-choice quiz: Shaping Earth's Surface Quiz

The Earth's surface is constantly being reshaped by powerful geological forces. Plate tectonics drive the formation of massive mountain ranges like the Himalayas and the Andes through collisions and subduction zones. Volcanic activity, much of which occurs underwater at mid-ocean ridges, creates new crust and volcanic arcs. Over millions of years, weathering and erosion wear down these tall peaks, making older mountains appear shorter and smoother. Additionally, sudden movements along faults can trigger catastrophic events such as earthquakes and tsunamis, while other features like impact craters are formed by external forces from space.
