P-waves are longitudinal / compressional waves and so can pass through both solids (rock) and liquids (magma).
Through cracks.
Magma seeps up through the two plates from the mantle and form volcanos.
The steam may come from magma relatively near the surface heating and boiling groundwater. Some gasses may come from the magma itself. The gas, being far lighter less viscous than the magma, can move through cracks even when the magma can't.
in a colliding boundary two plates move towards each other. one of the plates moves toards the magma and malts with it, because magma is less dense than the rocks on the plates the magma rises to through holes in the plate. gasses get trapped in the lava forming preassure of heat and magma and gasses, when the preassure becomes intense the magma explodes
Magma with less silica is thinner and runnier.Therfore, gases can move out of the magma easily.
Because nothing can be still and if more magma forms it has to push the rest away
Through cracks.
id say faults the answer is faults
it lets you move through walls and on magma etc.
they move because of the magma
Tectonic plates float on the magma of the Earth's mantle, and move because of convection currents in the magma.
They are found at a plate boundary. When two plates move apart (divergent) magma rises through the gap.
