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 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.utrophication occurs when a body of water has too many phosphates.  The most common source of phosphorus in lakes is from agricultural  run off. The second major cause is n â¦ atural due to high amounts of  organic materials falling to the surface of the water.
