Andes May Have Sprung Up in 'A Blink of An Eye'

A geologic "blink of an eye," to be specific, reports New Scientist. Mountain ranges, one would guess, grow over hundreds of millions of years, but according to a theory by University of Rochester scientists, it's possible the Andes grew 1.5 miles in just 4 million years, "a geological blink of an eye."

The growth spurt may have been caused by a "controversial geological theory" known as delamination. According to the theory, it's possible thick lower layers of a tectonic plate can drop off. When this occurs, the thin plate becomes unstable and crumples like the hood of a car in a crash.

About Me

My photo
I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
