- New plate material is being added to the edges of plates, and no plate material is being removed.
- Plate material is being removed from the edges of plates, and no new plate material is being added.
- New plate material is being added to the edges of plates, and the same amount of plate material is being broken into pieces and carried away.
- New plate material is being added to the edges of plates, and the same amount of plate material is being crumpled upward or recycled back into the earth’s interior.
