New crust forms at mid-ocean ridges.
New oceanic crust is created along mid ocean ridges. These are areas of the earth where there is divergence or splitting of the ocean floor and basaltic magma oozes out from within the mantle to occupy the gaps and form new crusts.
Divergent boundaries form ocean ridges.
Shallow focus earthquakes occur at the mid ocean ridges because the thin lithosphere found there is to weak to allow a large amount of strain to build up and cause larger earthquakes.
Just as new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.

New crust forms at mid-ocean ridges.
Mid-Ocean Ridges forms where a continental plate slides under an oceanic plate. I hope this is what your looking for ! ! !:D

It forms by the mid-ocean ridges under water or in the sea or ocean. () () (- -) ( ) UU
realate the high tempertures measured at the mid-ocean to the formation of basalt at the ridges
Mid-Ocean ridges.
New floor forms and spreads from mid-ocean ridges
1. between the continential crust and the oceanic crust 2. between two continential crusts (forms a mountain) 3. between two oceanic crusts (forms mid-ocean ridges)
New crust forms at spreading zones like the Mid-Atlantic ridge in the middle of the Atlantic Ocean. They occur because of ocean floor spreading.
They are called oceanic trenches.
