What are the different kinds of volcanoes?

    There are more than three types of volcanoes on Earth. "Volcanoes of the World" by Tom Simkin and Lee Seibert, lists 26 different types. For the sake of simplicity, I have chosen three listed below.

    The form of a volcano is determined by the composition of the erupting magma and the type of erupted products. Their shapes are determined to a large degree by the explosivity of the eruptions, and to the abundance of water and its degree of interaction with magma.

    SHIELD VOLCANOES

    CINDER CONES

    COMPOSITE VOLCANOES

    Most volcanic eruptions fall into one of a few main categories. Generally there are several types which include;

    1) cinder cones; the classic, cone-shaped peaks we commonly associate with a lava-spewing eruption

    2) shield volcanoes; A shield volcano (like Mauna Loa) owes its shape to the way the lava erupts from a vent in the earths crust that begins as a fissure, or crack. Pockets of superheated magma well up from beneath the crust, causing it to bulge upward. As the sea floor bulges from the movement of the magma, cracks form in the crust, sort of like the way the top of a cake cracks as it bakes in the oven. These fissures in the crust become weak areas of thin crust that give way to the upward force of the magma, eventually allowing it to break through. The overlying weight and pressure of the ocean water affects the way the magma emerges from fissures in the sea floor. The runny lava oozes out of the fissures and spreads out around the crack, cooling as it contacts the seawater. This slow and gradual accumulation of thin layers of lava build up over long periods of time, forming a long, shield-shaped volcano.

    3) stratovolcanoes; A stratovolcano also has steep sides with a distinguishing cone shape and is frequently composed of several different vents that erupt lava, sometimes in different ways. Pyroclastic flows*, lava domes**,and cinder cones sometimes characterize stratovolcanoes. Usually, these types of volcanoes erupt explosively and violently, sometimes completely blowing their tops!

    4) caldera eruptions; Caldera volcanoes are the Extreme Volcanoes. These are the most powerful and catastrophic types of volcanoes in a category by themselves because of the unique way in which they form. This type of volcano is shaped more like an inverse volcano. An enormous magma chamber bulges up beneath the ground from the extremely high pressures of the trapped gases within. Ring-shaped cracks form outward from the magma chamber toward the surface and these act as relief valves for the magma to escape. Once the accumulated pressure has been sufficiently released through a serious of extremely powerful pyroclastic and plinian eruptions, the ground above the magma chamber subsides or caves in, leaving a large depression. Caldera volcanoes are the largest on earth, with some calderas measuring from 15 to 100 kilometers wide.

    there's a cinder cone volcano, a composite volcano and a shield volcano. Cinder cone is for really explosive erruptions(and steep volcano. Peak) , composite for moderate (explosive, gentle)(what you think of when you think of volcanos), shield is gentle eruptions(the lava flows out slowly..)(very gentle slope)
