When lava first breaks through the surface of the Earth, it is an extremely hot liquid. On average, fresh lava can be between 1,300Â° F and 2,200Â° F! Depending on its exact temperature, fresh lava usually glows either orange/red (cooler) or white (hotter). Eventually, lava cools and returns to solid rock again.
Eutrophication is the process of increase of plant nutrients in water with the consequent. increase in the growth of algae and higher plants. This process is facilitated by external. and internal (such as nitrogen fixation) sources of nutrients. Input of nutrients may be. from point or diffuse sources.
The main focus and concern cause of eutrophication is nitrogen and phosphorus, but nitrogen has far more attention because it often limits primary production in estuaries and coastal waters and because the global application of nitrogen from synthetic fertilizers is far greater than that of phosphorus.e then focused this study on the impacts of eutrophication. Eutrophication is one of the main problems caused by an overuse of fertilizers and an excess of manure and sewage. These wastes enter the ecosystem and generally leach away from residential, business, and agricultural sites.
