Euthrophication is caused by excess nutrient run off, such as nitrogen or phosphorus. A common chemical that generally cause euthrophication is fertilizers from farm, if there's heavy rainfall or floods, they're easily washed into the rivers and lakes to cause euthrophication.
Euthrophication generally cause a sudden large scale algao bloom, or other plants, and they may cover the whole surface of water. Once these plants die, decomposers such as bacteria decompose them and take in oxygen for respiration, such that animals from the river originally may die due to lack of oxygen.
Answer:
V
Explanation:
During an El Niño event, the surface waters in the central and eastern Pacific Ocean become significantly warmer than usual. ... It also reduces the upwelling of cooler, nutrient-rich waters from the deep—shutting down or reversing ocean currents along the equator and along the west coast of South and Central America.

Air particles are a mixture of solids and liquids that are microscopically tiny and suspended by air currents. It can stay in the atmosphere for a few hours to a month or two. Their constituents can be various harmful substances such as heavy metals - lead, nickel, arsenic, cadmium or polycyclic aromatic hydrocarbons
Explanation:
Air particles, nitrogen dioxide and ground-level ozone are now considered to be the three most polluting substances in human health. Exposure during peak concentration and long-term exposure to these pollutants can cause damage from respiratory distress to premature death.
I believe the water will vaporize when it reaches a certain temperature. I'm not good in this subject, but I think I'm correct. Hope this helps. :)
