Can mountains form away from plate boundaries?

Best Answers

The best example I can think of would be the Rocky Mountains of western North America, thought to have resulted from plates completely subducting under North America, starting 80-ish million years ago. read more

Yes, hotspots form mountains far away from plate boundaries, like Hawaii. Also sometimes volcanoes can form from extension of the crust (decompression melting). This can occur far from plate boundaries. read more

Volcanoes that form above hot spots may be located away from tectonic plate boundaries. A good example would be the volcanoes forming the Hawaiian Island chain. read more

Mountains can form away from major fault lines (though I am pretty sure minor fault lines are almost universal) through the buckling of plate crust, or through volcanic hot-spot action. The Rocky mountains are an example of crust buckling that is not directly associated with major plate boundary fault lines. read more
