WORKSHEET
Topic – Ozone layer and its depletion
Class – VIII Subject: Science
Read the following paragraph on depletion of ozone layer and answer the questions based on it.
The ozone layer is a layer of the earth’s atmosphere in which most of the atmosphere’s ozone is concentrated. It protects the earth from harmful radiations like high energy UV – radiations from passing through it. Protective role of the Ozone layer in the upper atmosphere is so vital that scientists believe life on earth probably would not have evolved and could not exist today without it. In 1970, scientists discovered that chemicals known as chlorofluorocarbons can reach the stratosphere and destroy the ozone gas . Many common products and appliances such as aerosol spray, air conditioners and refrigerators release CFCs into the atmosphere when manufactured or used. In 1985 ‘scientists discovered that every year, the ozone layer over Antarctica becomes drastically thinner during the southern hemisphere’s spring, which forms an ozone hole over Antarctica. The hole occurs over Antarctica because the extreme cold conditioned help the very high clouds characteristics of that area to form tiny ice particles. When the polar winds blow, the chemicals in the air are trapped in the ozone layer. When the Antarctica spring sun rises in August or September and hits the trapped chemicals, a chain reaction begins in which chemicals such as chlorine and bromine react with ozone and destroy it quickly. When the ozone is depleted, more harmful UV Rays can penetrate the ozone layer and reach the earth surface. This can cause many health problems in humans.
1. How does the ozone layer of atmosphere protects lives on earth?
2. Why is the ozone layer getting depleted?
3. What do you mean by the ozone hole?
4. Can the ozone hole recover?
5. What are the harmful effects of depletion of ozone layer?

5-10 days. Make sure that you change the water every day after the paper has become soft
and pulpy take out the water and squeeze the pulp to drain out extra water. Now your
pulp is ready to be used. Mash it to make it smooth and give them shapes of the required
organelle. Keep them to dry in sunlight. After it gets dried up thoroughly paint them
accordingly.
