Abstract Lake Windermere :- A habitat to the Arctic Charr (Salvelinus alpinus). Windermere can be described as a glacial ribbon lake‚ which has experienced a lot of excavations and over deepening by past glaciations. Lake Windermere is (17 km) in length and over (1.5 km) in width. This is situated in the Lake District of Cumbria in the NW of England. It is (60 m) deep and falls withinthe wooded hills near Scafell and other mountains. Windermere is the largest lake in England. It is fed and replenished

Causes of air pollution There are many different chemical substances that contribute to air pollution. These chemicals come from a variety of sources. Among the many types of air pollutants are nitrogen oxides‚ carbon monoxides‚ and organic compounds that can evaporate and enter the atmosphere. Air pollutants have sources that are both natural and human. Now‚ humans contribute substantially more to the air pollution problem. Forest fires‚ volcanic eruptions‚ wind erosion‚ pollen dispersal‚

Reservoir defined The word reservoir refers to a place where large amounts of water get stored. The word reservoir comes from the French réservoir‚ which further derives from the Old French reserver‚ meaning "to reserve." Reservoirs are those water bodies formed or modified by human activity for specific purposes‚ in order to provide a reliable and controllable resource. a water body contained by embankments or a dam‚ and subsequently managed in response to specific community needs; or any natural

The water evaporates from all over the world but let’s say it is evaporates from the oceans to form clouds that are moved over land by many of winds. The rainfall then brings it to earth where it will return to oceans by creeks to river‚ and some lakes then back to the

Apparatus: boat Introduction: Lime cay is a small coralline cay that is mostly used by humans for their personal entertainment. By visiting this cay‚ man has had detrimental effects on the environment. In the earlier times‚ man’s impact was not so prevalent‚ however‚ overtime it has increased as agricultural practices and technology has been introduced. The effects can rise

Water pollution is the contamination of water bodies (e.g. lakes‚ rivers‚ oceans‚ aquifers and groundwater). Water pollution occurs when pollutantsare directly or indirectly discharged into water bodies without adequate treatment to remove harmful compounds. Water pollution affects plants and organisms living in these bodies of water. In almost all cases the effect is damaging not only to individual speciesand populations‚ but also to the natural biological communities. Introduction[edit]
