What is a pollution answer? ›

Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash. They can also be created by human activity, such as trash or runoff produced by factories. Pollutants damage the quality of air, water, and land.

A pollutant is a dangerous substance that is released into the environment. It can be released in a variety of ways and forms, such as toxic substances released into the land or water, carbon particles in smoke, or simply loud noises. A pollutant is a substance that disrupts the natural order of the environment.

Pollutants which are visible to our naked eyes are called visible pollutants. For example, sewage, plant and animal wastes, pesticides, plastic, sand etc.

Invisible pollutants are pollutants which are not visible to our naked eyes. For example, fungi, viruses, bacteria, gases like carbon monoxide, nitrogen dioxide etc.

Household combustion devices, motor vehicles, industrial facilities and forest fires are common sources of air pollution. Pollutants of major public health concern include particulate matter, carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Pollution is anything that makes the earth dirty and unhealthy. Land, air, and water are all affected by pollution. Pollution takes up space on our land. Many of the things people use every day come in packages, like food, games, school supplies, and electronics.

Polluting the Seas

Pollution is anything that is present or introduced into an environment which causes harm. In the sea there are many kinds of pollution such as rubbish, oil, chemicals and even sewage from toilets!

Air is not visible because it neither absorbs nor reflects light, it transmits whole of light. Dust particles in air is visible as they reflect light. Air is an almost perfect transparent substance.

Is water pollution visible? ›

Chemical released by manufacturing, cars, and lawns and farms are large contributors to water pollution but can be hard for students to identify because they may not be visible, or the source of the pollution is not easily connected to the area that is impacted.

In fact, most air pollution occurs at concentrations that are invisible and odorless, but still dangerous.

Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye.

Sand is a coloured solid, ground up into small particles. We cannot see through it.

Pollution disturbs our ecosystem and the balance and the balance in the environment. With rise of population and in increase in industries the problem of pollution is becoming more serious. Nowadays the air soil and water are polluted. The water of river is no longer suitable for drinking.

Pollution is when harmful things get into our environment and make it dirty. Sometimes, nature causes pollution, like when volcanoes erupt. But most of the time, people are the main reason for pollution. We create pollution when we drive cars, throw trash outside, and let factories release smoke into the air.

Pollution occurs when the pollutants contaminate the natural environment that affects life on earth adversely. With urbanization and development in our lives pollution has reached its heights giving rise to global warming. Due to global warming human beings, animals and our environment are adversely affected.

Pollution is the process of making the environment land water and air dirty by adding harmful substances to it. Pollution causes imbalance in the environment. This imbalance has threatened the very survival of all forms of life. It is a threat to the whole world.
