Air pollution occurs when harmful gases, dust, fumes or odors are present in the air. Heat trapping, also known as the greenhouse effect, refers to certain gases like carbon dioxide trapping heat in the lower atmosphere. Some key causes of air pollution and heat trapping include emissions from vehicles, power plants, wildfires, and household activities. This trapped heat leads to issues like rising global temperatures, sea level rise, and climate change. We can help address the problem through individual actions like conserving energy, limiting driving, and participating in conservation programs.

1. AIR POLLUTION AND HEAT TRAPPING
By:

2. DEFINITION
Air Pollution
• Air pollution occurs when the air
contains gases, dust, fumes or
odour in harmful amounts. That is,
amounts which could be harmful to
the health or comfort of humans
and animals or which could cause
damage to plants and materials
Heat Trapping
• When the sun’s rays hit the Earth’s
atmosphere and the surface of the
Earth, approximately 70 percent of
the energy stays on the planet,
absorbed by land, oceans, plants
and other things. The other 30
percent is reflected into space by
clouds, snow fields and other
reflective surfaces

3. TYPES OF AIR POLLUTION
Outdoor Activity
 Smog
 Particulates
 Acid rain
 Greenhouse Gases
Indoor Activity
 Usage of energy around the
house(carbon emission)
 Packaging household stuff

4. Pollutants
• Carbon Dioxide
• Carbon Monoxide
• Sulfur dioxide
• Nitrogen Dioxide
• Particulate Matter
• Lead

5. CAUSES
Natural sources
• Smoke that come from wildfires,
volcanoes, methane and dust
Human sources
• power plants and automobile, fumes,
burning wood stoves, fireplaces and
furnaces

7. WHATS RELATE PHYSICS TO THIS PROBLEM
• The greenhouse effect refers to circumstances where the short wavelengths of
visible light from the sun pass through a transparent medium and are absorbed, but
the longer wavelengths of the infrared re-radiation from the heated objects are
unable to pass through that medium. The trapping of the long wavelength radiation
leads to more heating and a higher resultant temperature. Besides the heating of an
automobile by sunlight through the windshield and the namesake example of
heating the greenhouse by sunlight passing through sealed, transparent windows, the
greenhouse effect has been widely used to describe the trapping of excess heat by
the rising concentration of carbon dioxide in the atmosphere

8. EFFECTS OF HEAT TRAPPING
• Environmental Effects.
 Eutrophication
 Rise in temperature
 Rise of sea level
 Depletion of Ozone Layer
 Global Climate Change

10. Ways to overcome this problem
• Campaign and activaty can be conducted by the government
• Reduce the usage of application that causes to the emission of carbon
• Conserve energy – remember to turn off lights, computers, and electric appliances
when not in use.
• Use energy efficient light bulbs and appliances.
• Participate in your local utility’s energy conservation programs.
• Limit driving by carpooling, using public transportation, biking and walking.
• Combine errands for fewer trips.
