Volcanoes
There are three types of volcanoes, Shield, Cinder Cone, and Composite. But first, what is a volcano? A volcano is kind of like a vent on the Earths Crust. It is a mountain that shoots out very, very hot magma or sometimes it might just explode. The part that shoots out the magma is called a vent and it is on the top. When talking about volcanoes, you might hear the word "dormant". A dormant volcano means that it is not active. You could also say that it is sleeping.
