How are Volcanoes formed

By:Snehit 7A

This is a diagram of how a land form is created

Deep inside the Earth's crust between the molten iron core and the thin crust at the surface, there is a very solid body of rock called the Mantle. When rock from the mantle melts, moves to the surface through the crust, and releases pent-up gases, then the volcanoes erupt.Extremely high temperature and pressure cause the rock to melt and become liquid rock or called Magma.When a large body of magma has formed, it rises through the denser rock layers toward Earth's surface. Magma that has reached the surface is called lava.An erupting volcano can trigger tsunamis, flash floods, earthquakes, mud flows and rockfalls.

THIS IS A VOLCANO ERUPTING!
