eruption

An eruption, typically referring to a volcanic eruption, occurs when magma from beneath the Earth's crust is forced to the surface. This process involves the build-up of pressure from rising molten rock, gases, and ash. When the pressure exceeds the strength of the overlying rocks, it causes an explosion or flow, releasing lava, ash, gases, and volcanic ash into the environment. Eruptions can vary in size and intensity, shaping landscapes and affecting climates. They are natural geological processes driven by the Earth's internal heat and tectonic activity.
