Explosions from composite volcanoes occur as a result of gas buildup within them. Shield volcanoes also may erupt explosively if water accumulates inside their vents.
The mid-ocean ridges are elevated above the surrounding seafloor because Ridge rocks are hot and therefore of relatively less dense than adjacent cooler oceanic crust.
I hope this helps you! :)
