| | Plate Tectonics : Mountain Ranges |
 | | The plates, therefore, emerging along mid-ocean ridges, sliding over the athenosphere, and grinding past other plates along transform faults, are almost all headed on a collision course. |
 | | Briefly, it goes like this: As the Indo-Australian Plate, with India firmly embedded, approached the Eurasian continent 20 million years ago, its leading edge, comprised of oceanic crust, was first to be crumpled and uplifted. |
 | | Thus, plate tectonics explains how the majestic peaks of one of the worlds great mountain ranges were once the deep sea-floors of an ancient drifting plate. |
