Air pollution is a mixture of solid particles and gases that can harm human health and the environment. It is caused by sources like energy production from fossil fuels, transportation emissions, and chemicals from factories. Long-term exposure to air pollution can lead to health issues like heart and lung diseases and even increase risk of death. While air pollution affects many areas, it is most common in large cities where emissions from many sources accumulate and form smog. Individual actions like taking public transit, biking, avoiding aerosols, and not smoking can help reduce air pollution levels. Renewable energy sources and new vehicle technologies provide alternatives to reduce pollution.
Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.

Air pollution: its causes,effects and pollutantsMaliha Eesha
This presentation gives the complete detail of air, air pollution, air pollutants and their types, each pollutant in detail and its causes and effects, acid rain, methods of prevention,smog,acidification,indoor pollution and so on. It is a complete package and I hope it'll be helpful in school! :)
Air pollution is the contamination of air by the discharge of harmful substances. Air pollution may be described as contamination of the atmosphere by gaseous, liquid, or solid wastes or by-products that can endanger human health and welfare of plants and animals, attack materials, reduce visibility or produce undesirable odors. As some pollutants are released by natural sources like volcanoes, coniferous forests, and hot springs, the effect of this pollution is very small when compared to that caused by emissions from industrial sources, power and heat generation, waste disposal, and the operation of internal combustion engines.
Air pollution is the introduction of particulates, biological molecules, or other harmful gases into Earth's atmosphere, causing disease, death to humans, damage to other living organisms such as food crops, or the natural or built environment. Air pollution may come from anthropogenic or natural sources.
: Air pollution is the presence of substances in ambient atmosphere, generally resulting from the activity of man in sufficient concentration, present for sufficient time and cause harmful effect on humans, plants and animals.

"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

2. Air Pollution
What is air pollution?
-The presence in the air of substances which pose
a potential threat to human health and/or the
environment.
-The presence of particles in the air which
decrease visibility
-The U.S. EPA estimates that 50 percent of the
U.S. population is exposed to air pollutants
exceeding current federal standards.
3. Sources and Types of Air Pollution
- Energy production from
fossil fuels
- Carbon dioxide, sulfur
oxides, particulates
- Increase in greenhouse
gases, acidic precipitation
4. Air pollution is a mixture of solid particles and gases in the air. Car emissions,
chemicals from factories, dust, pollen and mold spores may be suspended as
particles. Ozone, a gas, is a major part of air pollution in cities. When ozone
forms air pollution, it's also called smog. Some air pollutants are poisonous
5. More facts and Types of Air Pollution
-Automobiles, other
transportation sources
- Carbon dioxide, nitrogen
and sulfur oxides, products
of incomplete combustion
- Increase in greenhouse
gases, acidic precipitation
7. How does it affect life on Earth? Or how is
life on Earth affected by it?Long-term effects of
air pollution can last for years or for an entire
lifetime. They can even lead to a person's
death. Long-term health effects from air
pollution include heart disease, lung cancer,
and respiratory diseases such as emphysema.
Air pollution can also cause long-term damage
to people's nerves, brain, kidneys, liver, and
other organs. Some scientists suspect air
pollutants cause birth defects. 2.5 million
people die worldwide each year from the
effects of outdoor or indoor air pollution
12. Sources and Types of Air Pollution
