Question

discuss any 3 causes of volcanic eruption​

Answer 1

Answer:

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.

Answer 2

Answer:

When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions. In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge .
