Growth Spurt For Andes Mountains

National Geographic says the central portions of the Andes Mountains grew about 5,000 feet in as little as a million years.

Researchers at the University of Rochester in New York found that the growth spurt came after heavy rock that held the Andes in place fell into the mantle. The lighter, more buoyant crust then lifted about a third higher than their average height.

This rapid growth took place six to ten million years ago and may be in the process of repeating itself in the Andes of Argentina.
