Why are the Himalaya Mountains higher than the Andes Mountains?
“The Himalaya Mountains were formed geologically as a result of the clash of the Indian subcontinent with Asia. This process of plate tectonics is ongoing, and the gradual northward drift of the Indian subcontinent still causes earthquakes.” http://www.nepalguides.com/Geography.html Since the process is still happening up to now, the Himalaya Mountains continue to be higher and higher.
