  What is water pollution? Water pollution is the contamination of water bodies with harmful chemicals or microorganisms. Such impairment of surface water, groundwater, and coastal waters may be a result of stormwater runoff, industrial wastewater discharges, or sewer overflows.   Water pollution at times can be a source of drinking water contamination by pathogens or chemicals that have been dumped into the water supply. Water pollution also hurts fish and other marine life that live in the water.   Pollution has been traced back to both natural and man-made sources. The causes of some types of water pollution are agricultural runoff and poor sanitation practices. The first thing to do is to make sure that the water in your water source is safe to drink. Sometimes the pollution is not at the point of use. You can test your water supply by buying a bottle of distilled or boiled water, pouring it into the faucet or toilet, and then testing it again for a significant amount

what  is pollution? types of pollution in the atmosphere. We may not know exactly what to do about it, but we can recognize that even if all these pollutants were taken down completely and replaced by new substances without any additional energy inputs (the simplest way), our entire system would still be far more polluted than under existing conditions. Thus they also cannot simply avoid some risks: as long-term consequences from climate change will probably remain for millions or billions before reaching many humans on Earth. In my view, however naïve one might feel here, is there a very specific reason why natural selection must favor CO 2? This "global warming" effect has so little chance of being reduced because. types of pollution are more likely to have an effect than particles from other sources, especially the air we breathe," said R. Jayant Sharma, a professor at MIT's Sloan School and one for whose research CO 2 has been measured in human tissues duri

Deep in the earth, its temperatures are hot enough for a lot more rocks to melt slowly to become a dense fluid called magma. Because it's heavier than solid rock, magma rises and accumulates in magma chambers.  Eventually, some magma will reach Earth through cracks in a vent. Magmas that explode are called lavas. Occasionally the eruption has been explosive but not all.  Explosions depend upon a magmatic composition in the eruption. When magma is thin, gases may escape easily. In case a magma eruption occurs it is discharged from a volcano. Several examples of volcanic eruptions are in Hawaii. What is formed during volcanic eruptions are called lava flows? A volcano releases some of its hot gases when it erupts, creating smaller but powerful explosions that can travel for thousands or even millions (or hundreds) miles through the Earth's atmosphere and land below. As these molten gas particles move up into the stratosphere they expand rapidly—and explode explosively at high alt
