location of volcanoes
Plate edges may be either oceanic crust or continental crust. So when plates collide, we have only three possibilities: oceanic-oceanic, oceanic-continental, or continental-continental collisions. [ Locations of Volcanoes: page 1 / page 2 ...

The Colorado Plateau Region (part 1 of 4)
F.A. Barnes, an expert on the region's geology. "As a distinct mass of continental crust, it is at least 500 million years old -- probably a lot older." Such longevity is ... when one considers the globetrotting adventures of the North American continent from the perspective of continental drift theory. Over a period of 300 to 400 million years, while the land mass ...
