How does human affect the nitrogen cycle?

Humans impact the nitrogen cycle by using fertilizer and chemical additives in the soil creating an increase in nitrogen as well as by burning fossil fuels which creates a dramatic increase in nitrogen.

What is the difference between cooling towers and pollutants chimneys?

cooling towers usally just release steam, due to the fact that product (air, water, oil, etc...) travels through some kind of piping or duct work with water or air passing around or across it inturn cooling the product where as polluntant chimneys, are exits for exhaust emmissions from things like dust collectors or large kilns or furnances where particles from the product being made is heated or cooked,and all of the particles cannot be contained.

Does nitrogen pollute the air?

Nitrogen is a normal component (about 80%) of the air you breathe. It is inert under most circumstances (excluding deep sea work where nitrogen narcosis or Rapture of the Deeps, might occur)

When there is too much nitrogen in the air, it is usually looked at as too little oxygen.

Though nitrogen is a naturally occurring in air, nitrogen oxide, which is mainly produced by road traffic. In excess it is known to give rise to acid rain. The main affect of NO2 in air is that it contributes to the formation of photochemical smog. It can also cause respiratory problems because it causes inflammation of the lining of the lungs and reduce immunity to lung infections

How much of the world's CO2 emissions does us produce?

Factory pollution is over 40% of the pollution that causes global warming. One of the diseases that it causes is asthma. More than twenty million people a year have asthma attacks and over 9,000 kids in the United States die a year from asthma attacks. Other diseases are heart and lung diseases, and respiratory allergies ("Drgreene.com"). The World Health Organization estimates that in all 4.6 million people die each year from causes that are directly from air pollution.

According to Scorecard, over 20,000 factories in the United States produce over 4 billion pounds of toxic chemicals that could leak into the environment.

How did humans add dangerous isotopes to the environment?

"Un-Natural" isotopes are released by open air detonation of nuclear weapons; gases escaping from nuclear reactors; improper containment and storage of radio active wastes; use of isotopes for medical treatments (very low amounts emitted). "Natural" isotopes are released by volcanic activity, open pit and deep shaft mining, geothermal springs, oceanic floor rifts, created by collision with cosmic rays, ultraviolet decomposition or chemical re-arrangement of atmospheric molecular structures, etc.

What scientist studies pollution?

Someone who describes himself or herself as a pollution scientist is likely to be voluntary working out of social ethical motivation with out pay. and not for a government or multinational. There is no formal qualification title but many specialists an interdisciplinary, chemistry or medical background is useful. Medical and related to effects on Humans would be called a toxicologist. A broader chemistry and environmental background is an ecotoxicologist and is interested in pollution of animals and plants.

An ecologist:)

Effects of tsunami?

1.It causes death and sickness.

2.It destroys human properties.

3.It causes floods and landslide.

4.People will be homeless.

5.Evacuation centers will over crowded.

How is the U.S restricting emission of greenhouse gases?

The United States does not have the overall largest carbon footprint. That distinction belongs to China, with its massive industry sector and 1.5 billion residents. The US, does, however, have the largest footprint per capita.

What radioactive emission is easiest to absorb?

Alpha particles are the easiest to absorb because they have the largest mass and charge compared to beta and gamma radiation. This makes them less penetrating and easier to stop with just a sheet of paper or skin.

How does oil effect plants?

If you were to water a plant with oil and even some amount of water to go with it, the plant would soon die in less than a week even. The time it would take for a plant to die would depend on what type of plant it is. If you haven't realized yet, the plant affected with oil will not live longer but die sooner than expected. This is my answer, and I hoped it helped all of you questioning people in wonder of it.

Which gas is produced by power station?

Power stations typically produce carbon dioxide gas as a byproduct of burning fossil fuels like coal, oil, or natural gas. This greenhouse gas contributes to climate change when released into the atmosphere in large quantities.

Describe the formation of acid rain?

1.acid rain is another bad effects if burning of fossil. fuels by man acid rain.

2. acid rain is can kill plants.

3. If it falls in to lake it can kill fish.

4. It can damage materials made in bricks metal or stone.

5. when sulfur dioxide combined with drops of water in the acid rain informed..

What are the effects of restaurants on the environment?

To supply meat for their burgers they have to have space to keep their cattle and let them graze. Sometimes-mostly-there isn't enough space so they send people to chop down big areas of the forest therfore affecting the animals who live in trees, the food chain and lots more and when they have a bigger amount of livestock they cut down even more trees and repeting the process.

What is the range of pH in acid rain and how this is linked to the concentration of acid?

Strong acids have high pH, so If the concentration of acidic elements in the rain high, the pH of the rain solution is higher.

"In chemistry, pH is a measure of the acidity or basicity of an aqueous solution." Wikipedia

Note from a chemistry teacher on the answer above:

Several of my pupils have referenced this answer in their Coursework - it is WRONG!!!!

Strong acids eg HCl, are completely dissociated and therefore have a high concentration of H+ ions. Weak acids are only partly dissociated and so have a lower concentration of H+ions.

The pH scale is a measure of the concentration of H+ ions but because it is calculated using the negative log of the concentration, the LOWER the pH the HIGHER the concentration of H+ ions

So, answer above should read = strong acids have a LOW pH so if the concentration of acidic elements in the rain is high then the pH of the rain solution is LOWER

PS - kids - Wikianswers is not always the best place to use for your coursework - take care!!!!!

Where does overpopulation occur?

Overpopulation occurs when the number of those born exceeds that of those who die over a long period of time. In human societies, overpopulation occurs in regions where people traditionally have very large families and at least adequate healthcare. Older civilizations, such as India and China, tend to have large populations because they've been around for a long time, they've been relatively stable and progressive (with healthcare at least), and their aggregate childbirths exceed the aggregate death rate.

Is brass biodegradable?

No, brass is a metal that will stay for thousands of years in landfills and rubbish dumps without breaking down.

Is lead biodegradable?

Yes, in olden times, when cars used lead net in the smoke valve of the cars, at that time, it released a lot of smoke into the air. If one wanted to dispose it, he needed a lot of effort to do so. So, lead vapour is a non- biodegradable pollutant. Now a days too burning lead is poisonous thing and is a hateful thing to do to the workers. It releases CO2 in the air also.

How does acid rain effect living organisms?

Acid rain can make the soil too acidic, which may mess up the growth of certain crops. When acid rain falls into lakes, it can poison the water supply for any marine life, as well as animals that drink from that water source.

How many fish die of water pollution every year?

The UN Environment Programme estimates that about one million seabirds and 100,000 marine mammals every year are killed by plastic debris, which can include not just plastic bags, but syringes, cigarette lighters and toothbrushes, all of which have been found inside the stomachs of dead seabirds.

What effect does acid rain have on the organisms in the environment?

"If you are in AP Bio then you should have been paying more attention in class. Precipitation is rain, acid precipitation is therefore acid rain. Acid rain is harmful to plants, animals, and fish. Even buildings are affected. It is ACID therefore corrosive and deadly. Sorry if I come across as rude but try to make the most of your education."

Wow that guy/girl is really annoying. He/she even posted the same answer on yahoo. I recognize this question from the study guide for Chapter 3, #9. I looked on a lot of websites about acid precipitation and non of them said anything about it being a benefit to organisms. So i assume that it was a typo or something.

How do humans affect forests?

earthquakes, floods, avalanche, volcanoes, hurricane, landslide all of them will effect people, people lose their homes their loose their animals pets precious things to them and people get hurt so it really does affect people.

How does research and technology affect the environment?

The industrial revolution and the use of fossil fuels has, as an example , allowed us to cut down forests rapidly, deplete fish stocks, pollute the air and waterways, and all these things threaten biodiversity. But , technology can also help us turn the corner and repair the damage being done by our use of non-renewable energy. For instance, computers and satellites are helping scientists to understand how human activity is affecting the planet, and technology has found ways of harnessing renewable energy, and growing food more efficiently. The internet has hightened environmental awareness , and the importance of maintaining biodiversity.

Does the U.S have air pollution?

Yes because of s many factories polluting our air, that are letting out plumes of chemical filled smoke. Other things that pollute our air is smoking, cars, trucks, anything that lets out a fume or gas that have chemicals.
