For nearly 60 million years, our home planet was likely frozen into a big snowball. Now, scientists have discovered evidence of Earth's transition from a tropical underwater world, writhing with photosynthetic bacteria, to a frozen wasteland – all preserved within the layers of giant rocks in a chain of Scottish and Irish islands.
Glaciers form when repeated annual snow fall accumulates deep layers of snow that are not completely melted in the summer. Thus there is an accumulation of snow that builds up into deep layers . P erennial snow is a snow accumulat ion that lasts all year .
Snow falls in the accumulation area, usually the part of the glacier with the highest elevation, adding to the glacier's mass. As the snow slowly accumulates and turns to ice, and the glacier increases in weight, the weight begins to deform the ice, forcing the glacier to flow downhill.
