Volcanic eruptions occur when pressure builds beneath the Earth's surface, forcing molten rock, gas, and ash to escape. Magma rises through cracks in the crust, forming lava flows, explosive eruptions, or ash clouds that can impact global climates. Different types of volcanoes, such as shield, stratovolcano, and cinder cone, produce varying eruption styles. Some eruptions create new landmasses, while others cause widespread destruction. Scientists monitor seismic activity, gas emissions,...
