Orogen

Orogen is a hands-on plate tectonics sandbox. Watch mountains rise, trenches open, volcanoes form and faults slip, one process at a time. Pick a boundary and a scenario, then press play. A cross-section of the Earth shows what happens as plates converge, diverge or slide past each other. Drag the time slider to move backward and forward through millions of years. 6 SCENARIOS Ocean-Continent: an ocean plate sinks beneath a continent, forming a trench, a volcanic arc and a mountain belt. Ocean-Ocean: a chain of volcanic islands grows above a sinking plate. Continent-Continent: two continents collide and raise a mountain range. Continental rift: a continent stretches and splits as a new ocean opens. Mid-ocean ridge: new sea floor forms and spreads. Transform fault: two plates lock, build strain and slip in an earthquake. Every stage has a short, plain explanation on screen, and a narrator…
