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 a process in which bodies of water (lakes, ponds, and rivers) receive excess nutrients that stimulate excessive growth of algae.The two most common nutrients that initiate eutrophication are nitrogen and phosphorous, two limiting nutrients in the growth of algae.utrophication is a noun that refers to the excessive richness of  nutrients in water body or a lake. The excessiveness is due to  frequent runoff from the land that causes â¦ dense growth of plant  life. It can be caused naturally or by human.
