Volcanoes essay

There are seven types of volcanic eruptions: Strombolian, Vulcanian, Peléan, Hawaiian, Phreatic, Plinian, and subglacial. A Strombolian eruption, named after Stromboli in Sicily, consists of large blobs of magma thrown tens to hundreds of meters in the air, until they fall to the ground and produce short, viscous streams of lava.

In conclusion, volcanoes are cracks in the Earth’s crusts where magma has reached the surface and turned into lava. There are about 500 volcanoes spread out all over the world, and above are just a few of the most well-known ones.
