Eruptions - PowerPoint PPT Presentation

Volcanic eruptions are caused by the release of pressure inside the Earth, leading to the expulsion of magma through volcanic vents. This process results in the formation of cone-shaped mountains or hills known as volcanoes. The magma, which originates from the asthenosphere, rises through cracks in
