Volcano Wallpaper Free Amazing Volcano and Magma Pictures HD LiveWallpapers! A volcano is a rupture in the crust of a planetary-massobject, such as Earth, that allows hot lava, volcanic ash, andgases to escape from a magma chamber below the surface. Earth'svolcanoes occur because its crust is broken into 17 major, rigidtectonic plates that float on a hotter, softer layer in its mantle.Therefore, on Earth, volcanoes are generally found where tectonicplates are diverging or converging. For example, a mid-oceanicridge, such as the Mid-Atlantic Ridge, has volcanoes caused bydivergent tectonic plates pulling apart; the Pacific Ring of Firehas volcanoes caused by convergent tectonic plates coming together.We have added these Wallpapers are eye drops.
