The distribution of mid ocean ridge across the globe provides the primary indicator of boundaries between all tectonic plates.

Explanation:

The tectonic plates are solid piece of lithosphere that ranging the thickness from 5-10 km present in deep ocean which from the earth's crust.

Earth's outer most layer is fragmented and form tectonic plate and lithosphere contain crust.

The mid ocean ridge is located in sea floor and is formed by tectonic plates which contain a depth of about 2,600 meters and spreading by divergent plate boundary.

The uplifting of ocean floor occur when current rises beneath the oceanic crust in the mantle that creates magma.
