Question

Describe the causes of volcanic eruptions in long

Answer 1

so I have got 3 reasons for the causes of volcanic eruptions

first one is that through cracks and fissures in the Earth's surface water gets into the Earth surface and it tends to melt the soft rocks inside the Earth surface which turns into hot Magma and flow out as Lava on to the Earth surface


second one is that the as pressure inside the earth surface is very much as compared to the ground level so the magma tends to come out on the surface of the Earth due to the pressure difference


and the third one and the most simple one is the movement of tectonic plates
