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 caused by excessive nutrients in the water causing the depletion of oxygen supply and death of water organisms.this is due to the soil rich in nutrients washed away to the water because there are no trees to hold the soil intact. for short, it is caused by deforestation...blue_13 Â· 9 years ago.utrophication is caused by excessive nutrients in the water causing the depletion of oxygen supply and death of water organisms. this is due to the soil rich in nutrients washed away to the water because there are no trees to hold the soil intact. for short, it is caused by deforestation... blue_13 Â· 9 years ago.
