According to Christopher R. Scotese, the movement of the San Andreas Fault will cause the Gulf of California to flood into the Central Valley. This will form a new inland sea on the West Coast of North America, causing the current locations of Los Angeles and San Francisco to merge.[54][failed verification] The Californian coast will begin to be subducted into the Aleutian Trench.[55]
Africa's collision with Eurasia will close the Mediterranean Basin and create a mountain range similar to the Himalayas.[56]
The Appalachian Mountains peaks will largely wear away,[57] weathering at 5.7 Bubnoff units, although topography will actually rise as regional valleys deepen at twice this rate.[58]
