What are the physical differences between a cinder cone, a shield volcano, and a stratovolcano?

1st answerer is good on location.  Difference between the types are due to the composition of the lava and where they occur.\n\nShield volcanoes, such as those found in Hawaii, have magma that is very low in silica, high in basalt (often referred to as "basaltic" volcanoes).  This means that the lava flows easily, instead of exploding.  That is why there is not a steep slope to the volcano and the biggest threat is just to remain out of the lavas way.\n\nStrato-volcanoes (Mt. St Helens) are found in subduction zones and produce a lava that is described as Andesitic (named after the Andes Mountains in South America).  This lava is high in Silica, which makes it much more viscous, and therefore, more explosive.  This explosiviness defines the shape of the cone, with much steeper sides.  With these types of volcanoes you have the explosive lava threat, but you are also threatened by pyro-clastic flows, and lahars.\n\nCinder cones are the same, compositionally as strato-volcanoes, but are not always located in a subduction zone, and are usually quite alot smaller.

I found a different website that talks about all the different types of volcanos.  There  are Shield volcanoes, Strato, Rhyolite caldera, Monogenetic fields, Flood basalts and Mid-ocean ridges.  There was also some interesting volcano facts that you might be able to use at the 2nd website below.

Curiously, I could not find a comprehensive listing.  This site might be helpful, however, or at least give you a start.\n\nhttp://dir.yahoo.com/Science/Earth_Sciences/Geology_and_Geophysics/Volcanology/Volcanoes

Hawaii and Iceland are examples of places where volcanoes extrude huge quantities of basaltic lava that gradually build a wide mountain with a cone-like profile. Olympus Mons is the largest cone volcano on Mars, and is the tallest known mountain in the solar system. Smaller versions of cone volcanoes include lava cones, and lava mounds.\n\nQuiet eruptions spread out basaltic lava in flat layers. The buildup of these layers form a broad volcano with gently sloping sides called a shield volcano or a cone Examples of shield volcanoes are the Hawaiian Islands.

It's a stratovolcano:\nhttp://volcano.und.nodak.edu/vwdocs/volc_images/img_mt_pelee.html

A stratovolcano is a tall, conical volcano composed of many layers of hardened lava, tephra, and volcanic ash. These volcanoes are characterized by a steep profile and periodic, explosive eruptions. The lava that flows from them is highly viscous, and cools and hardens before spreading very far. The source magma of this rock is classified as acidic, or high in silica to intermediate (rhyolite, dacite, or andesite. or basalt). This is in contrast to less viscous basic magma that forms shield volcanoes (such as Mauna Loa in Hawaii), which have a wide base and more gently sloping profile. Many stratovolcanoes exceed a height of 2500 m.\n\nStratovolcanoes are a by-product of the subduction of tectonic plates. The source melts of these volcanoes arise as a result of the dewatering of oceanic crust at specific pressure/temperature conditions as the plate subducts to lower depths. The water freed from the subducting slab allows partial melting of the overlying mantle rock, which rises due to its lower density relative to the surrounding mantle rock, and pools at the base of the crust. The melt is initially basic in composition. As it rises through the crust, it incorporates more acidic adjacent crustal rock, leading to a final intermediate composition. The water remains in the melt and upon eruption contributes to the explosive power of these volcanoes as superheated steam.\n\nAlthough stratovolcanoes are sometimes called composite volcanoes, volcanologists prefer to use the term stratovolcano to distinguish among volcanoes because all volcanoes of any size have a composite (layered) structure — that is, are built up from sequential outpourings of eruptive materials.

First, the difference between magma & lava...they are both molten rock but it is called magma beneath earth's surface & lava when it has been extruded from the earth.\n\nIntrusive igneous rock is formed from magma beneath the earth's surface. Because it is forming below the surface, it will take longer to cool. When igneous rock is allowed to cool slowly the crystals will have time to grow larger before the rock cools completely. This process may take a very long time. The texture will be either fine-grained, coarse-grained, or porphyritic. Examples are granite & diorite.\n\nExtrusive igneous rock is formed from lava above the surface of the earth. Because it forms outside the earth, it cools much more quickly. When igneous rock cools very quickly it will take on a glassy texture. This means that it has very very tiny to no crystals whatsoever. Examples include volcanic glass (obsidian) & pumice.

when a volano explodes it erupts lava.The lava is very hot but it still cant melt the volcano.The lava will cool off,forming a rock.Rocks that are formed when lava cools is called a Igneuse rock.It is very hard to melt a intire volcano.If the lava melts the volcano at all,only a little bit of the inside would be melted. the lava just dries up

vent-is an opening in which gasses especially air can pass.\nmagma chamber-is where the magma kept and because of the heat and pressure,magma is pushed upward ,magma that is outside,is called the lava.\ncrater-the big hole where lava came out\n\ni think thats all i can give\n\ngood luck

Impact crater characteristics to look for:\nShocked minerals\noverturned bedding in ejecta blanket\ncircular shape (nearly always)\nlow rim relief over surrounding areas\nbottom of crater lower than surrounding plain\n\nVolcanic crater characteristics:\nlooks like a mountain (high rim relief)\nvolcanic materials present\ndoes not have to be circular \noften multiple craters within caldera  \nbottom of crater higher than surrounding plane\nno shocked minerals

Volcano is the result of Lava and gases gushing out of the surface of the earth at great heat and pressure.  The molten lava is running over the land and destroy the plants and trees and after cooling becomes rock there. Fresh lava  comes out and run in the available slope.  The result is a mountain is growing with fire and lava.  Thus the mountains are the result of volcano and lava.  When the pressure within the volcano is reduced the volcano takes rest.It will erupt at any time  and send lava and gases, fire in all the directions.  The centre of the earth is believed to contain very hot lava and gases which is likely to come out at any time in any part; and most likely in the soft surfaces .

Here is one:\n\nhttp://etap.org/newsletter/volcano/shield.jpg\n\nBut just type ¨shield volcano¨  in google images (I just did) and you can choose between hundreds.
