- 3. *AIR SUPPLIES US WITH OXYGEN WHICH IS ESSENTIAL FOR OUR BODIES TO LIVE. * THERE ARE SEVERAL MAIN TYPES OF POLLUTION.THESE INCLUDE SMOG, ACID RAIN ,THE GREEN HOUSE EFFECT AND, HOLE IN THE OZONE LAYER . *ONE TYPE AIR POLLUTION IS THE RELEASE OF PARTICLE INTO THE AIR . *ANOTHER TYPE POLLUTION IS THE RELEASE NOXIOUS GASES. *POLLUTION ALSO NEED TO BE CONSIDERED INSIDE OUR HOMES, OFFICES AND SCHOOL. 3 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 4. SMOG * SMOG IS A TYPE OF LARGE-SCALE OUTDOOR POLLUTION. IT IS CAUSED BY CHEMICAL REACTION BETWEEN POLLUTANTS DERIVED FROM DIFFERENT SOURSES. * CITIES ARE OFTEN CENTERS OF THERE TYPES OF 4 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 5. * IT IS CAUSED WHEN A POLLUTANT COMBINES WITH DROPLETS OF WATER IN THE AIR. * THE EFFECT OF ACID RAIN ON THE ENVIRONMENT CAN BE VERY SERIOUS. 5 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 6. * IT GENERALLY COMES FROM THE BUILD UP OF CARBON-DIOXIDE GAS IN THE ATMOSPHERE. CARBON-DIOXIDE IS PRODUCED WHEN FUEL ARE BURNED. * IN THIS TYPE OF POLLUTION SUN RAYS GO INTO THE ATMOSPHERE AND THEY ARE TRAPPED BY GREEN HOUSE GASES. SO THE TEMPERATURE ON THE EARTH RAISE. 6 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 7. IT IS ANOTHER RESULT OF POLLUTION. CHEMICAL RELEASED BY OUR ACTIVITIES EFFECT THE STRATOSPHERE. RELEASES OF CFC FROM HEATING, AEROSOL CANS,REFRIGERATION EQUIPMENT REMOVES SOME OF THE OZONE, CAUSING HOLES. 7 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 8. *IT IS MORE DANGAROUS THAN THE OUTDOOR POLLUTION, BECAUSE WE DO EVERYTHING IN ENCLOSED ENVIRONMENTS WHERE AIR CIRCULATION MAY BE RESTRICTED. * THERE ARE MANY SOURCES OF INDOOR AIR POLLUTION: TABACCO SMOKE, COOKING AND HEATING APPLIANCES AND VAPORS FROM BUILDING MATERIALS. 8 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 9. * SOME INDIVIDUAL ARE MUCH MORE SENSITIVE TO POLLUTANT THAN ARE OTHERS. * AIR POLLUTION CAN AFFECT OUR HEALTH IN MANY WAYS WITH BOTH SHORT-TERM AND LONG-TERM EFFECTS. 9 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 10. * The fact is that human activities contribute the most to air pollution. Considering the harmful effects of air pollution, now it is very essential that everyone should contribute a bit to prevent air pollution. There are certain ways that one can help to reduce the emission of air pollutants in the atmosphere. Following are some tips for preventing air pollution: Car Pool: Forming and implementing a car pool will reduce the number of cars, thereby, preventing air pollution by cutting down the use of fossil fuels. This way, it will help in the sustainable use of fossil fuel and its conservation for the future generations. 10 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
- 11. Vehicle Care: Timely servicing of the car helps to keep it in a good condition and also minimizes fuel exhaust. Driving the car at an average speed and turning off in traffic is a key to save fuel. Make sure to use unleaded petrol and opt for regular pollution checking of your car. Public Transport: Whenever possible, try to travel by public transports. This helps in two ways; prevents air pollution and increases public income. If you are going to a nearby place, go by walking or use bicycle, instead of using your vehicle. The objective is to minimize the use of fuels, as far as possibl 11 NAME- ROHIT CLASS - VII-D ROLL.NO - 21
