A volcanic eruption can be violent, pushing huge amounts of ash and gas high into the sky, but some eruptions are less dramatic, producing long, oozing flows of runny lava volcanoes can form steep cone shapes or have gentle, sloping sides. Shield volcanoes, the third type of volcano, are built almost entirely of fluid lava flows flow after flow pours out in all directions from a central summit vent, or group of vents, building a broad, gently sloping cone of flat, domical shape, with a profile much like that of a warrior's shield. The three main types of volcanoes are composite, shield and cinder cone volcanoes each type of volcano is formed a different way and possesses specific characteristics indicative of its type composite volcanoes, also called stratovolcanoes, consist of lava flows that are mixed with sandy layers of.

Describe and compare different volcano types and the processes that form them in this section, you will learn the different types of volcanoes, how they are formed and where they are commonly located. Volcano eruptions happen when magma erupts from beneath the earth's crust when a volcano erupts, the magma becomes lava and shoots into the air, eventually running down the side of the volcano to understand how and why volcanoes erupt, we must first understand the different layers of our planet. Types of volcanoes the form, or shape, of a volcano is governed by the composition of erupting magma and type of erupted products (volcaniclastic products of various kinds such as pyroclastic and autoclastic fragments or effusive lava.
When most people think of volcanoes, they think of a tall mountain with a crater on the top, maybe a little snow at the summit and some trees scattered around the base there are many volcanoes like this, but volcanoes exist in many other forms as well each type of volcano has characteristic.
