The age of oceanic bedrock on either side of a mid-ocean ridge is supporting evidence that at the ridges, tectonic plates are Diverging .

Explanation:

The underwater mountain range is the mid oceanic ridge, which were formed as a result of plate tectonics.  when the convection current goes up in the mantle present beneath the oceanic crust results in the uplifting of the ocean floor.

Which leads to the formation of the tectonic plates through magma, that meet at divergent boundaries. The density and the age and the thickness of these oceanic crust increases due to the distance from the ridges. The mid oceanic ridges has been split on two sides as matching stripes ,
