Glaciers are gigantic bodies of ice and snow sediments that accumulate overtime, slowly moving due to its own weight. The formation of glaciers begins when excessive amounts of snow gathers in a certain areas. Overtime the snow transforms into ice. Under the influence of its own weight and gravity, it starts to flow downwards, and upwards, creating bumps and slopes.
