Sediments get thicker with increasing distance from the ridges.

There is not enough lithosphere on the earth to account for what has been produced in the last 200 million years. Lithosphere is created at divergent boundaries and the earth is not getting any larger. The moon is moving away from the earth and this would not happen if the earth had more lithosphere to increase its mass.
