volcanic eruption theory
A volcanic eruption occurs when magma from beneath Earth's surface rises through cracks in the crust due to pressure from the Earth's interior. When the magma reaches the surface, it erupts as lava, ash, and gases, shaping the landscape. Factors like the magma's composition, gas content, and the structure of the volcano influence the eruption's intensity and style. The process releases energy accumulated over long periods, periodically creating new landforms and reshaping existing ones. This natural activity is driven by tectonic plate movements that generate the pressure needed for magma to break through the Earth's surface.
