One of the most natural disasters on the earth, 'Volcano'. Earth's is extremely hot. This high temperature is due to disintegration of radioactive materials found there, chemical processes and upward pressure. In this way, the material starts melting at a greater depth and comes out by breaking the weak parts of the ground floor, which causes a volcanic eruption. This causes a sudden explosion on the ground floor, through which lava, gas, smoke, ash, pebbles, stones, etc. come out. All of the Volcanoes are born in the internal parts of the Earth, which we cannot see directly. Therefore, to find the different phases of the Jawalamukhi eruption, we have to resort to external facts. So take this quiz on the great volcano and increase your knowledge about it.
