What is a Volcano? Created by Brian, Joey, and Steven

== Volcanoes are considered to be mountains formed where tectonic plates collide, or separate. They are rips in a planet’s surface or crust. When a volcano erupts, lava piles up near a volcanic vent. It cools, and becomes a clump of rock. At the bottom of a volcano lies a magma chamber. Magma flows through a passage called the conduit, and comes out of the volcano. A spurt of lava can fly 30 kilometers high. When a volcano erupts, heat can also escape. Also, a volcano eruption can cause massive weather change. Ashes can also let people find breathing pretty hard. This will make crops inedible. Also, some people live within the “danger zone” of some volcanoes because of the rich soil. ==

== There are dormant and active volcanoes. A dormant volcano also known as an inactive volcano has a low percentage of erupting at the moment. Active volcanoes can erupt any minute. There is no certain interval between two eruptions, logically. Volcanoes can form on land, or in oceans. When a sea volcano erupts, the lava cools and turns into an island. This process can take centuries. There is also a volcano on Mars! The Pacific Ring of Fire is a group of volcanoes near the Pacific Ocean that form when tectonic plates come together. Small series earthquakes can be an aftershock of an eruption. ==

== Volcanoes are sure marvelous things Mother Nature can offer! For more information you can search from Google, or visit www.volcanoes.com, www.factmonsters.com, www.woodlands-junior.kent.sch.uk, www.bing.com, www.yahoo.com, www.answer.com, or www.wikipedia.org. ==
