volcanism

Volcanism refers to the processes by which volcanoes form and erupt. It occurs when magma from beneath the Earth’s surface rises to the surface, often due to tectonic plate movements. When the pressure builds up, it can lead to an eruption, releasing lava, ash, and gases. This can create new landforms, including volcanic mountains or islands. Volcanism plays a significant role in shaping the Earth’s landscape and can impact climate and ecosystems. Understanding volcanism helps us prepare for potential hazards and appreciate the dynamic nature of our planet.
