Coldest Glaciers Help Mountains Grow

Dubbed "glacial armoring," researchers discovered that the coldest glaciers protect mountains, allowing them to grow taller (*note: glaciers normally cause the erosion of mountains). Studying the Andes mountains, they found that the northern and warmer area eroded much faster in comparison with the southern and colder area. This is because colder glaciers don’t move much, thereby sealing the mountains and preventing erosion.
