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.
Eutrophication. Eutrophication is the process by which a body of water becomes overly enriched by nutrients. You can recall this term by remembering that the word 'eutrophic' comes from the Greek language and means well-nourished. Therefore, a body of water that has undergone eutrophication is a 'well-nourished' lake.utrophication is typically the result of human activities that contribute excess amounts of nitrogen and phosphorus into water. Agricultural fertilizers are one of the main human causes of eutrophication.
