From Towering Rockies to Erupting Fury: Can You Conquer This U.S. Mountains & Volcanoes Quiz?

Beneath your feet, tectonic plates grind like slow-motion titans, thrusting the Rockies skyward at 1 mm per year while subduction feeds the Cascades’ fiery chain. America hosts 10% of the world’s active volcanoes and its tallest peak outside Asia—yet most lie dormant, hiding cataclysmic power. Did you know Yellowstone’s caldera could fit Tokyo inside, or that Mauna Kea, measured from seafloor, dwarfs Everest? This quiz unearths the science: how shield volcanoes ooze basalt oceans, why stratovolcanoes explode with andesitic fury, and which U.S. summit holds glaciers thick enough to survive climate change. From plate boundaries to eruption chemistry, test your grasp of Earth’s most dynamic classroom!
