Volcanoes and the hazards they bring!
Volcanoes Volcanoes form when magma rises through cracks in the Earth’s surface. Pressure builds up inside the Earth. When this pressure is released, magma explodes to the surface causing a volcanic eruption. The lava from the eruption cools to form new crust. Over time, the rock builds up and a volcano forms. Volcanoes occur at destructive and constructive boundaries. Volcanoes… Continue reading Volcanoes and the hazards they bring!
