What is volcanic eruption and its causes?
Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. This lighter magma then rises toward the surface by virtue of its buoyancy.
What can you say about volcanic eruption?

Why there is a volcanic eruption?
Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth’s mantle melts. If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises. When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.
What is effect of volcanic eruption?
