what causes volcanic eruption??? ​

Answer 1

Answer:

here's the answer:-

• 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.

Answer 2

Answer:

On the ground where we live there is a layer of rock. This layer is called the earth's crust. The layer is formed from a number of large plates. Beneath the plates there is a mixture of rock or magma. Sometimes, the boiling rock rises between the plates and causes volcanic eruptions.
