What is happening at oceanic spreading ridges?

A mid-ocean ridge or mid-oceanic ridge is a submarine plateau range, created by plate tectonics. This uplifting of the ocean level happens when convection courses increase in the mantle underneath the oceanic crust and generate magma where two tectonic plates assemble at a divergent boundary.

It also produces the spreading ridge which is the displacement zone along the ocean ground where hot mantle element reaches to the surface, thus forming new crust. This fracture can be seen underneath the ocean as a line of hills that constitute as molten rock stretches the ocean floor and compresses.

this would be a math
