Answer

Brief Explanations:

Volcanic eruptions occur when pressure in a magma - chamber forces magma through cracks in the Earth's crust. Explosions in magma chambers build up the necessary pressure for the magma to be ejected out as lava during an eruption. Magma turning into lava is a result of the eruption, water being heated by magma is a secondary effect, and magma cutting through older rocks is part of the process but not the main cause of the eruption.

Answer:

explosions occurring in magma chambers
