Description

Over multiple decades this continued accumulation of snow leads to the presence of an oversized enough mass of snow for the geological process from snow to ice mass ice process to start. Glaciers are classified by their size (i.e. ice sheet, ice cap, natural depression ice mass, corrie glacier), location, and thermal regime (i.e., polar vs temperate). Glaciers area unit are sensitive indicators of fixing climate. A Glacier originates at a location known as its Glacier head and terminates at its ice mass foot,snout, or terminus [1].

An ice mass may be a massive, perennial accumulation of crystalline ice, snow, rock, sediment, and sometimes liquid water that originates on land and moves down slope underneath the influence of its own weight and gravity. Typically, glaciers exist and should even type in areas where

• Mean annual temperatures area unit near to the freezing point

• Winter precipitation produces important accumulations of snow

• Temperatures throughout the rest of the year don't show in the overall loss of the previous winter’s snow accumulation

Glaciers area unit broken into zones based on surface snowpack and melting conditions. The ablation zone is that the region wherever there is a net loss in ice mass. The higher part of an ice mass, wherever accumulation exceeds ablation, is named the accumulation zone. The equilibrium line separates the ablation zone and also the accumulation of coastal zone [2]. It is the contour wherever the quantity of latest snow gained by accumulation is capable the quantity of ice lost through ablation. In general, the build-up zone accounts for 60%-70% of the glacier's area, additional if the ice mass calves icebergs. Ice within the accumulation zone is deep enough to exert a downward force that erodes underlying rock. Once ice mass melts, it typically leaves behind a bowl or amphitheater shaped depression that ranges in size from massive basins just like the Great Lakes to smaller mountain depressions referred to as cirques.

Sea level is rising, in part, as a result of melting glaciers onto land area and adding additional water to Earth’s oceans.

Glaciers massive sheets of ice and snow exist on land all year long. They are found within the mountains of each continent except Australia Greenland and Antarctic continent contain large ice sheets that also are thought-about glaciers. As temperatures rise, glaciers soften quicker than they accumulate new snow. As these ice sheets and glaciers soften, the water eventually runs into the ocean, inflicting water level to rise. Icebergs and frozen seawater melts due to higher temperatures however they are not important contributors to water level rise. This can be as a result of they are already within the water. The amount of water they displace as ice is concerning identical because the volume of water they increase the ocean once they soften. As a result, water level doesn't rise once ocean ice melts. whereas density variations between salt water and fresh end in a distinction between the amount of salty ocean water being displaced by ocean ice and also the fresh that might result from the melting of that ocean ice, its lowest and on the far side the scope of this lesson [3]. Another contributor to low-lying rise is that the increase in volume that happens once water is heated, known as thermal enlargement. Each thermal enlargement and ice soften area unit the results of the increase in international average temperatures onto land and ocean referred to as temperature change. As glaciers melt from climate change, their contents namely, large quantities of freshwater, sediment, and nutrients are slowly released into coastal ecosystems [4].

Conclusion

CO₂ (carbon dioxide) is one in every of the most causes of all misfortunes of the planet, like heating, that causes the melting of glaciers, floods, and tsunamis. The most “producers” of dioxide area unit significant industries, energy production facilities that combust oil, coal and gas, general cutting of tropical forests, stock business, and of course, United States-the same old folksthe customers. Cut back the consumption of natural resources, reduce the emissions of harmful substances into the atmosphere, and preserve the purity of water and forests.
