Course[change | change source] The river starts from a glacier called Gangotri Glacier‚ which is in the Garhwal region in Himalayas. The Ganges flows through north India‚ and ends at the Bay of Bengal in eastern India. Overall it flows 3‚877 km making it one of the longest rivers in the world. Its watershed is 907‚000 km²

changes in species composition over time in a previously uninhabited environment. When primary succession begins no soil exist; rock surfaces like volcanic lava and glacier scraped rock surfaces are the platform on which primary succession begins. In figure 4.4 of the text Primary succession is happening on glacier moraine after the glacier has deposited rocks‚ gravel and sand. Pioneer Community is the initial community that develops during the primary succession process. Lichens are the most important

previous half century could be attributed to greenhouse gas emissions produced by human activities (i.e.‚ industrial processes and transportation). Many scientists predict that such an increase in temperature would cause polar ice caps and mountain glaciers to melt rapidly‚ significantly raising the levels of coastal waters‚ and would produce new patterns and extremes of drought and rainfall‚ seriously disrupting food production in certain regions” (Wojtal-frankiewicz‚ 2012). “Other scientists maintain

Broad and flat‚ plains are well named. Some appear when glaciers and streams erode away elevated terrain; others spread where rising magma pushes‚ erupts‚ and spews. Some plains spill into the oceans‚ and others are bound by mountains on several sides. They all hide a tumultuous geologic history beneath their level disguise. The base of the vast Great Plains in North America formed when several small pieces of continental crust collided and welded together more than a billion years ago. As time

The Rivers of France The Rhône system The Rhône is the great river of the southeast. Rising in the Alps‚ it passes through Lake Geneva (French: Lac Léman) to enter France‚ which has 324 miles of its total length of 505 miles. At Lyon it receives its major tributary‚ the Saône. In eastern France the direction of the main rivers is predominantly north-south through the Alpine furrow. The regime of the Rhône is complex. Near Lyon the Rhône and its important Isère and Drôme tributaries‚ draining

The loss of large areas of ice on the surface could accelerate global warming and because less of the sun’s energy would be reflected away from Earth t. resulting in melting glaciers and a rise in sea level (Strickland‚ Grabianowski‚ 2005) melting of ice glaciers are causing serious treats to Greenland and Antarctica. The rise in sea levels could cause flooding problems for low- lying coastal areas‚ but if Antarctica ice sheet were to melt of collapse into the sea
