Does the oceanic lithosphere get older or younger as you move closer to
the mid-ocean ridge?

Yes,

The oceanic lithosphere thickens as it ages and moves away from the mid-ocean ridge. ... As a result, the oceanic lithosphere is much younger than the continental lithosphere: the oldest oceanic lithosphere is about 170 million years old, while parts of the continental lithosphere are billions of years old.

I hope my answer help,

God blessed you

some think that theories become laws, but theories and laws have separate and distinct roles in the scientific method. a law is a description of an observed phenomenon in the natural world that hold true every time it is tested. it doesn't explain why something is true; it just states that it is true.

it would be kevlar ^^
