In Mr. Gonzalez's class we learned that ther is 3 different types of volcanoes and 4 different types of lava. Well thefirst volcanoe I learned about is the  Composite volcanoes and they can can usually get up to tens of miles across and up to ten thousand or more feet height. Next, is the Cinder coneand are usually small volcanoes, about a mile across and about a thousand feet high and they usually have a small crater on top.The Shield volcano, gets hundreds of miles across and tens of thousands of feet high. Next up, there is Low water/ Low silica, Low water/ High silica, High water/ Low silica and High water/ High silica. The Hawaiian islands are high water and low silica and Mt. St. Helens is low water and high silica. By Dominic B
