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.
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.
Younger. The mid-ocean ridge is formed from new material being thrust up from inside the Earth.
Oceanic lithosphere gets older as it moves away from the mid-ocean ridges where new lithosphere is formed. This process, known as seafloor spreading, causes older lithosphere to be pushed further from the ridge, resulting in a gradient of lithosphere age with the oldest being farthest from the ridges.
Yes, new oceanic crust is formed at mid-ocean ridges through a process called seafloor spreading. Magma rises from the mantle through the ridge, cools and solidifies to form new crust. This process helps in constantly renewing the oceanic crust.
