There are many different types of volcanoes. Some form tall mountains, while others are part of large plains.Mountainous Volcanoes that rise from the ground fall into a few basic categories.The stratovolcano, also called a composite cone, is the type of volcano that usually comes to mind when someone says “volcano.” It’s the classic, cone-shaped mountain with a crater on top. Mount Etna in Italy, Mount St. Helens in the United States, Mount Cotopaxi in Ecuador, Mount Fuji in Japan, Mount Pinatubo in the Philippines, and Krakatau in Indonesia are a few examples. The crater can be either a caldera or a hole blasted out during a violent eruption.
