of the motion of continental plates for the last 750 million years.
Some Future Consequences of Plate Tectonics
Plate tectonics is still an active process, and will drastically
reshape the face of the Earth over the next 50 million years or so. A few consequences
of plate tectonics based on projections of present motion include: 
- Portions of California will separate from the rest of
North America.
- The Italian "boot" will disappear.
- Australia will become linked to Asia.
- Africa will separate from the Near East.
As a consequence of plate tectonics (supplemented by wind and
water erosion), we live on the surface of a geologically active planet that
has obliterated most of its early geological history.
