The first type of volcano I learned about was composite volcano. Are typically tens of miles across, and tens of thousand feet of height. The next volcano I learned about is the cinder cone volcano. The cinder cone volcano mainly consists almost entirely of loose grainy cinders and almost no lava. Another volcano I learned about was the shield volcano. The shield volcano is type of volcano that can be hundreds of miles across and many tens of thousands of feet high. This volcano is mainly found in Hawaii. The next volcano I learned about is the caldera Volcano. Calderas, which are simply circular depressions that are found in summits of many volcanos. The last volcano I learned about is the fissure volcano. Fissure Volcanos make large cracks in the ground instead of a giant crater like most volcanos.

I also learned about different lava types. The first lava type I learned about is low water/low silica. Low water/low silica is lava that is very thin and runny lava. The next lava I learned about is low water/high silica. One of the most important factors is composition espescially the amount of silica melted in lava results in a thick lava. Another lava type I learned about is high water/low silica. This type of lava (high water/low silica) produces a spectacular “fire fountain” directly over the vent usually resulting in a cinder cone any remaining lava quietly flows away. The last type of lava is high water/high silica. This type of lava causes explosions eruptions at volcanos like Vesuvius and Mt St Helens.
