The ocean floor doesn't sink from just age alone. As time passes, the plates under the ocean floor continue to move, and eventually they sink under the Earth's mantle in the process of subduction.
It gets older.

sea-floor spreading
The oldest rocks on the continents would be much older than the rocks on the sea floor because the rocks on the continents are not being removed unlike the rocks on the sea floor that are made by the mid-ocean ridge are being removed by deep ocean trenches. this prossess that is occuring on the sea floor is called sea floor spreading. evidence of this is the Pacific ocean shrinking and the Atlantic ocean growing.

The oldest layers of sea floor would exist at the bottom of the Marianas Trench, where oceanic plate subduction is occurring. The subducting oceanic plate is less than 200 million years in age.

No. The sea floor is much younger than the continents. The oldest sea floor is about 200 million years old. The continents are billions of years old.

Depth of the sea floor. For example at 30,000+ feet of depth, it becomes increasingly difficult to drill for oil on the open sea.
seafloor spreading, age of the sea floor and ocean trenches.
The scientists realized that the continents were much older, leading them onto the theory of Sea Floor Spreading!
