Mountain ranges rise much more rapidly than geologists expected

A new study suggests mountain ranges like the Andes can rise rapidly, doubling their heights in a short period. The traditional theory of plate tectonics will need to be revised to include the process of delamination, which proposes that the 'root' beneath the crust heats up and breaks free, allowing mountains to quickly rise.
