Glaciers are defined as a persistent body of extremely dense ice that forms over millions of years in result of very cold temperatures that occurred on Earth during the Ice Age. The formation of Glaciers results when an abundance of snow exceeds its melting and sublimation point over many centuries. However, the introduction of global warming to the Earth is causing an adverse effect on all glaciers around the world, thus riding the world of the essential necessities glaciers have provided us for multiple centuries. Glaciers hold the largest amount of surface freshwater on Earth and make up 10% if land area. Places that hold the majority of glacier bodies are Antarctica, Greenland and the Canadian Arctic. In Figure 6.3 of “Elemental Geosystems” it is explained how out of the percentage of water on Earth only 2.78% is Freshwater. However ice and glaciers make up 99.357% of the surface freshwater. Making them the greatest storage unit of freshwater on Earth (Christopherson & Birkeland, 2016). In essence the North and South poles are important storage units containing almost all of the freshwater located on Earth. With how large glaciers become (the weight of the new snow that forms on top and the lower solid ice part) causes it to move downhill.

It was one of these Glaciers that sank the…
