Coastal Mountain Ranges--In Which the Mountains are the Coast
One of the ways to create a major mountain range is a process called subduction.
Here, heavy oceanic rock sinks beneath the lighter continental rock. The result--coastal mountain ranges like the Andes, the Aleutians, the Japanese and the Southern Alps.
But look closer...
Between the Pacific Ocean and the Andes Mountains are lowlands. Narrow, undeniably, but still closer to sea level. So the question is this--is it possible for a mountain range to be the beach rather than at least a few miles inland? And if the answer is yes, then what force of geology would I need to make that possible?
