I'm just enjoying the movement of this thread. . .

 

 

When two oceanic plates collide, the younger of the two plates, because it is less dense, will ride over the edge of the older plate. Volcanic Island Arcs form at subduction zonesThe older, heavier plate bends and plunges steeply through the athenosphere, and descending into the earth, it forms a trench that can be as much as 70 miles wide, more than a thousand miles long, and several miles deep. The Marianas Trench, where the enormous Pacific Plate is descending under the leading edge of the Eurasian Plate, is the deepest sea floor in the world. It curves northward from near the island of Guam and its bottom lies close to 36,000 feet below the surface of the Pacific Ocean.

If the descending oceanic plate is carrying a continent, the less dense continental material cannot sink, so it dives into the trench behind the leading oceanic crust until it gets stuck. This crumples its leading edge into folded mountains and causes some of the oceanic crust of the overlying plate to be deposited on top of the continent. Pressure steadily builds up until the trench
