Tectonics
Plate Tectonics
Plate tectonics is a scientific theory explaining the movement of Earth's lithospheric plates over the asthenosphere, leading to the formation of continents, mountains, earthquakes, and volcanoes.
Volcano
A volcano is a vent and associated landform where molten rock, ash, and gases from Earth’s interior reach the surface. Most volcanoes are concentrated at tectonic plate boundaries, though some occur above mantle hotspots, and eruptions range from effusive lava outpourings to highly explosive events with significant hazards to people, infrastructure, and climate.
