As the oceanic lithosphere moves away from a mid-ocean ridge, it cools and thickens. This process causes the ocean floor to become older and denser, resulting in its gradual subsidence. The farther it gets from the ridge, the deeper the ocean floor becomes due to the increased thickness and weight of the lithosphere.
New oceanic lithosphere forms as a result of seafloor spreading at mid-ocean ridges. Magma rises from the mantle, solidifies at the mid-ocean ridge, and creates new oceanic crust. This process leads to the continuous expansion of the ocean floor.
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
When divergence occurs in the oceanic lithosphere, it leads to the formation of mid-ocean ridges where new crust is created as magma rises from the mantle and solidifies. This process is responsible for the spreading of the ocean floor and the formation of new oceanic crust.

Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge
under water volcanoes move the oceanic plates and spread them
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
