What happens during sea floor spreading?

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other heat from the mantle’s convection currents makes the crust more plastic and less dense. The less-dense material rises often forming a mountain or elevated area of the seafloor. Eventually the crust cracks.
