New oceanic lithosphere is constantly being produced at mid-ocean ridges and is recycled back to the mantle at subduction zones.

* POOR. Our Quality Ratings refer to the production values in the movie, the entertainment quality of the production, and whether the movie fulfills what it tries to do. A four-star rating does not guarantee that the movie will meet our criteria for what makes a truly fine, much less great, work of art. That kind of criteria depends a lot on oneâs moral and spiritual values, issues that our Acceptability Ratings (see below) are meant to address. Acceptability Ratings: +4 to -4.
