LONG QUESTION ANSWER :

Question. Describe a Volcano, explain its various parts with the help of diagram?
Answer : A Volcano is a vent or opening in the earth’s crust through which molten material erupts suddenly. Magma and other volcanic materials are chann- eled to the surface where they expelled through a crack or hole. The three main parts of a volcano are the chamber ,vent ,and the crater. Way below the surface of the earth is the crust, where volcanic activity begins . Mag- ma is contained in magma chamber. A space within the earth that holds the hot melted rock. Magma also contains gasses, that start to build up pressure over times. When the pressure becomes extreme,the magma is pushed out of the earth through main vent, somewhat like pipeline. The magma shoots through this pipeline in order to escape the earth. A crater is formed when the volcano literally blows its top ,pushing out anything on the earth’s surface, e.g. the Deccan Plateau in India.
