Difference between magma and lava?
Magma=melt at depth

The rate at which heat rises from the earths interior up through the crust, is not the
same everywhere in the ocean.

Plate tectonics: earths major plates move at slow, continues rate.
Cooler, denser slabs of oceanic lithosphere descend into mantle
