- On question four is the magma gathering up to exploed?(4 votes)
- Yep! The magma from the melting subducting oceanic plate is gathered and floats upwards because of convection currents formed by the Earth's core. It's then squeezed into cracks of the Earth's crust, making the magma chamber, and then it's waiting to be build up further to the point of explosion.(4 votes)
