Explanation:
At one end, new crusts are being produced, at other end the crust is being destroyed and this strikes a unique balance.
At the mid-ocean ridges, the lithospheric plates are diverging. This is implies that the earth is pulling apart here. When the earth is pulling apart, new materials from the asthenosphere comes to the surface thereby creating new lithospheric plate.
As new plates are formed, they push back against the old one. New plates are found very close to the margin and it begins to age away from the margin.
On the other end, old plates are taken away from this center to ocean trenches. At oceanic trenches subduction is occurring.
In a subduction, the lithospheric plate plunges deep into the asthenosphere where they are being melted back.
This is a covergent margin.
This process continues in a dynamic manner to cycle matter on earth.
