volcanoes

what types of volcanoes are there 

• Cinder Cone Volcanoes: These are the simplest type of volcanoes are the simplest type of volcano. They occur when particles and blobs of lava are ejected from a volcanic vent. The lava is blown violently into the air, and the pieces rain down around the vent. Over time, this builds up a circular or oval-shaped cone, with a bowl-shaped crater at the top. Cinder cone volcanoes rarely grow larger than about 1,000 feet above their surroundings.

• Composite Volcanoes: Composite volcanoes or stratovolcanoes make up some of the world's most memorable mountains: Mount Rainier, Mount Fuji, and Mount Cotopaxi, for example.
Shield Volcanoes: These are large, broad volcanoes that look like shields from above – hence the name. The lava that pours out of shield volcanoes is thin so it can travel for great distances down the shallow slopes of the volcano. These volcanos build up slowly over time, with hundreds of eruptions, creating many layers. They’re not likely to explode catastrophically. Perhaps the best-known shield volcanoes are the ones that make up the Hawaiian Islands, especially Mauna Loa and Mauna Kea.
• Lava Domes: Volcanic or lava domes are created by small masses of lava which are too viscous (thick) to flow very far. Unlike shield volcanoes, with low-viscosity lava, the magma from volcanic domes just pile up over and around the vent. The dome grows by expansion of the lava within, and the mountain forms from material spilling off the sides of the growing dome. Lava domes can explode violently, releasing a huge amount of hot rock and ash
