Pollution
Pollution is the process of giving out contaminants such as smoke and carbon dioxide, and too much of a certain product such as light, heat and sound that both cause harm to the environment.

How much pollution does launching a spaceship cause?
Not a great deal because the main fuels are hydrogen and oxygen, so the exhaust is merely water-vapour. Solid propellants will produce other gases that may be polluting, but the number of launches world-wide, and the individual volumes of gas, are very small compared to anything else.
What is emitted mainly during a nuclear detonation?
Shockwaves and thermal radiation are mainly emiited in a nuclear detonation. When the nuclear blasts hits the ground, kinetic energy from the impact will be released, similar to an earthquake, causing shockwaves. Thermal radiation, or electromagnetic radiation, a result of energy released from the nuclear reaction of two nitrogen atoms forming a carbon and an oxygen atom, causes fires, thermal burns and blindness.
littering happens when people are careless and throw their trash anywhere
fuel burning except in vehicles
How does oil spills affect duckweed growth?
Oil spills are very bad for Duckweed growth. This is because duckweed need oxygen and oil spills keep oxygen from reaching the plant.
Why do people think that the BP oil spill was all BP's fault?
They didn't maintain the link well enough and also instead of getting right onto it they sat around waiting for someone else to come do it for them. They could have stopped it in just under 3 days using a method of setting concrete on top of the leak or of course the most simplest method (SWITCHING THE PUMPS OFF). But that would have cost them more money.
Gun pollution is the proliferation, in the social sphere, of guns and rifles that cause and increase fear, pain, or death to humans and animals.
Is the greatest source of air pollution volcanic eruptions or burning fossil fuels?
Definitely the burning of fossil fuels. Volcanoes emit around 100,000,000 tons of CO2 a year. Man-made emissions of CO2 comes to about 10,000,000,000 tons of CO2 per year. So volcanoes emit around 1/100th of CO2 that we do.
What the cause of unequal distribution of water in Africa?
THere are places where water is abundant, and the people living there get to consume it. They don't have the money to create good enough infrastructure to pipe the water to places where it is less abundant.
When will the results of 13th National science olympiad come?
the results are going to come online on 22 nd January 2011
What is a pollution free energy resource?
All energy resources are pollution free. It is extracting some of the energy from those resources that causes pollution. Extracting energy, by any means, from any resource, will cause pollutions of some kind somewhere in that cycle.
There is no way to extract energy from anything without doing so in some way.
Why does a geothermal power station not need cooling towers?
Because the excess steam is condensed into water and and goes back underwater where it is reheated for later use.
Plastics do not all behave the same as their composition and additive packages vary. Some have densities greater than water and would sink, others have densities less than water an float. many of the commonly encountered plastics (polyethylene,, polypropylene, etc.) fall into this latter classification. Higher density plastics include Silicones with densities ranging from 1.68 - 2.00 g/cm3
Answer - Mostly humans cause pollution. Of course nature causes a certain amount of pollution naturally but not to the extent of being harmful to us at the moment.
Improper sanitation or poor sanitation refers to the unhygienic condition that might affect the environment. The most common disease that poor sanitation may cause is diarrhea.
A single car give off how much pollution?
It depends on the amount driven. Every liter of gasoline burned releases about 2-3 kg of carbon dioxide and nitrogen oxides. That's 16 to 20 lb per gallon for Americans who aren't metrified.
What are the solutions Ocean pollution?
Answer
you could build a dome around your communtiy to protect it from ocean pollution
Answer:
The control of pollution of the oceans is simple, in a way: Create less, don't dump material into the sea.
However some ocean pollution problems have gotten away from us:
- Carbon dioxide in the water is changing the H affecting marine organisms. Control will reuire all of the global warming solutions to recuce carbon dioxide emissions and time for natural processes to reduce the concentrations.
- Oil pollution is endemic over the seas. The removal f floating oils and emulsified ils will require natural removal and human interventon whereever the concentrations become high enough.
- Plastics in the ocean accumulate in the famous "trash vortexes" and will require mechanical harvesting and recycling to remove them
How does leaded petrol harms the environmrnt?
It doesn't. Environmentalists just want us to believe it does.
How does pollution that leads to the death of plant plankton can affect life on earth?
Plankton are at the very very bottom of the food Chain. So, if they go extinct then whatever is the next up the food chain will become extinct and so on. If Plankton go extinct, life as we know it is over.
What is indoor noise pollution?
Indivisible houses can create noise pollution, Cardiff Council's had studied and says that Noise is one of the most pervasive pollutant. A musical clock may be nice to listen during the day, but may be an irritant during sleep at night. Noise by definition is "sound without value" or "any noise that is unwanted by the recipient". Noise in industries such as stone cutting and crushing, steel forgings , loudspeakers, shouting by hawkers selling their wares, movement of heavy transport vehicles, railways and airports
It is therefore of utmost importance that excessive noise is controlled. Noise level is measured in terms of decibels (dB). W.H.O. (World Health Organization) has prescribed optimum noise level as 45 dB by day and 35 dB by night. Anything above 80 dB is hazardous.
Sources of noise pollution:
Noise pollution is a growing problem. All human activities contribute to noise pollution to varying extent. Sources of noise pollution are many and may be located indoors or outdoors.
Indoor sources:include noise produced by radio, television, generators, electric fans, air coolers, air conditioners, different home appliances, and family conflict. Noise pollution is more in cities due to a higher concentration of population and industries and activities such as transportation. Noise like other pollutants is a by product of industrialization, urbanization and modern civilization.
Noise can be one person's enjoyment and the cause of another's headache. The level and frequency of noise will be acceptable to one person and not to another. Excessive noise can reduce a person's quality of life, causing sleepless nights, stress and in some cases, anger.
The council has a duty to investigate complaints of noise issuing from a domestic or commercial premises, a vehicle alarm or mechanical equipment, under the Environmental Protection Act 1990 Part III - Statutory Nuisance and the Noise Act 1996. We are unable to deal with complaints relating to road traffic or public order offences.
Effects of noise pollution:
Noise pollution is highly annoying and irritating. Noise disturbs sleep, causes hypertension (high blood pressure), emotional problems such as aggression, mental depression and annoyance. Noise pollution adversely affects efficiency and performance of individuals.
What are advantages of acid rain?
There are NO advantages in acid rain. Acid rain has dissolved the harmful fumes from factory and vehicle pollution to turn neutral rain into acid. This acid then damages plants, animals, landscapes and buildings as it falls to earth.
Is siltation a pollution in water?
Siltation is a form of water pollution it is caused by the particles of soil, silt and clay entering the river, or lake or practically any body of water, it is caused by soil erosion and the process can typically be accelerated by farmers or construction sites of nearby areas of bodies of water, in other words by human activity. This can cause an entire ecological system to fall apart and cause species of aquatic fish such as the endemic species of the cichlids (a species of fish) or even coral reefs of the sea for example. So in short yes siltation is a form of water pollution and it may also be named sediment pollution.
