it is caused by convection currents
they are related because they all have to do with the oceanic lithosphere.The convection causes the lithosphere to move sideways and away from the midocean ridges.The ridge push makes the oceanic lithosphere slide downhill under the force of gravity. The slab pull:the old lithosphere is denser than asthenosphere so, the edge of the tectonic plates that contains oceanic lithosphere sinks and plls the rest of the tectonic plate.

A Mid-Ocean-Ridge develops leading to volcanism and the creation of new oceanic crust.
One of the midocean ridges is, but others are in other oceans, seas, and bays.

it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
Ridge Push.
Younger. The mid-ocean ridge is formed from new material being thrust up from inside the Earth.
Magma rises and slidifies and creates a new crust.
