Definition of Volcano : A Volcano is an opening on the surface of the earth that emits gases, volcanic ash and hot Magma. Most of the time, the reason for the eruption of any Volcano is the crunching or sliding of Tectonic plates.The person who study the process of eruption of volcanoes are known as volcanologists.
Types of Volcanoes
volcanoes can be classified on the basis of their shape, material and the way it ejects the lava.
Majorly there are 5 types of volcanoes explained below:
1. Cinder Cone Volcano – Cinder cone is the most found type of volcano that forms a steep conical hill above a vent, due to the gas-charged lava, blown violently into the air.
2. Shield Volcano – Shield Volcano is a doomed shape volcano with long, gently sloped sides . These volcanoes spread in a broader area but do not grow tall due to the composition of lava which is very fluid.
3. Composite Volcano (or Strato volcanoes) -These volcanoes are formed through clusters of vents in the earth ,from which lava flows comprising of volcanic ash, blocks, and bombs. With all this material coming out, these can grow thousands of meters tall.
Some of the most beautiful mountains in the world are Composite Volcanoes such as Mount Shasta in California, Mount Fuji in Japan, Mount Hood in Oregon and Mount Rainier in Washington.
4. Complex Volcano (also called compound volcano) – These are formed because of the changes in the characteristics of eruption , different locations and multiple vents in the earth surface. The composite volcanoes can form the complex volcanoes.
5. Spatter cones – A spatter cone is formed, when gases in lava are good enough to prevent the formation of lava flow, but not able to shatter it into small fragments. The lava breaks into the fluid i.e.hot clots called the “spatter”.
