Another 1.3 inches per year is locked up at the plate boundary, squeezing South America, and is released every hundred years or so in great earthquakes. About 0.3 inches of motion per year crumples South America, building the Andes..
In this manner, are the Andes growing?
It's been understood that the Andes mountain range has been growing as the Nazca oceanic plate slips underneath the South American continental plate, causing the Earth's crust to shorten (by folding and faulting) and thicken.
Subsequently, question is, how are the Andes formed? The Andes were formed by tectonic activity whereby Earth is uplifted as one plate (oceanic crust) subducts under another plate (continental crust). To get such a high mountain chain in a subduction zone setting is unusual, which adds to the importance of trying to figure out when and how it happened.
Likewise, why are the Andes so high?
Other theories have been advanced for why the Andes are unusually high. Researchers have suggested it is because there are no rivers to wash sediments into the trench between this subducting plate and the continent, creating an unlubricated zone with extra friction to prop up the mountains.
How far do the Andes stretch?
about 4,500 miles
