"what is ozone layer and ozone hole?" in   Tuition/Class IX-X Tuition

The ozone layer is a deep layer in the stratosphere, encircling the Earth, that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun. Interestingly, it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen, made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates the two atoms in an oxygen molecule (O2), which can then individually recombine with other oxygen molecules to form ozone (O3). The ozone layer became more widely appreciated by the public when it was realized that certain chemicals mankind manufactures, called chloroflurocarbons, find their way up into the stratosphere where, through a complex series of chemical reactions, they destroy some of the ozone. As a result of this discovery, an international treaty was signed in 1973 called the Montreal Protocol, and the manufacture of these chemicals was greatly reduced. The ozone layer has since begun to recover somewhat as a result of these efforts, but there is some science which now suggests that the major volcanic eruptions (mainly El Chichon in 1983 and and Mt. Pinatubo in 1991) which have occurred since we started monitoring ozone with satellites in the late 1970's, could have also contributed to the ozone depletion. The amount of stratospheric ozone overhead on any given day and at any given location varies quite a bit. Because of vertical circulations of air in both the troposphere and the stratosphere, there can be greater or lesser amounts of ozone protecting you from ultraviolet radiation. Also, living at higher elevations exposes people to more UV radiation than at low elevations. While stratospheric ozone which protects us from the sun is good, there is also ozone produced near the ground from sunlight interacting with atmospheric pollution in cities that is bad for human health. It causes breathing problems for some people, and usually occurs in the summertime when the pollution over a city builds up during stagnant air conditions associated with high pressure areas. The ozone hole is not technically a “hole” where no ozone is present, but is actually a region of exceptionally depleted ozone in the stratosphere over the Antarctic that happens at the beginning of Southern Hemisphere spring (August–October). Satellite instruments provide us with daily images of ozone over the Antarctic region. The ozone hole image below shows the very low values (blue and purple colored area) centered over Antarctica on 4 October 2004. From the historical record we know that total column ozone values of less than 220 Dobson Units were not observed prior to 1979. From an aircraft field mission over Antarctica we also know that a total column ozone level of less than 220 Dobson Units is a result of catalyzed ozone loss from chlorine and bromine compounds. For these reasons, we use 220 Dobson Units as the boundary of the region representing ozone loss. Using the daily snapshots of total column ozone, we can calculate the area on the Earth that is enclosed by a line with values of 220 Dobson Units.

"what is 3R , related to environment protection?" in   Tuition/Class IX-X Tuition

The Three R's of the Environment Every year, Americans throw away 50 billion food and drink cans, 27 billion glass bottles and jars, and 65 million plastic and metal jar and can covers. More than 30% of our waste is packaging materials. Where does it all go? Some 85% of our garbage is sent to a dump, or landfill, where it can take from 100 to 400 years for things like cloth and aluminum to decompose. Glass has been found in perfect condition after 4,000 years in the earth! We are quickly running out of space. It's time to learn the three R's of the environment: reduce, reuse, recycle. Then practice what you preach: don't buy things you don't need or items that come in wasteful packaging or that cannot be recycled. Reuse and recycle whatever you can. Reduce Reducing the amount of waste you produce is the best way to help the environment. There are lots of ways to do this. For example: Buy products that don't have a lot of packaging. Some products are wrapped in many layers of plastic and paperboard even though they don't need to be. You can also look for things that are packed in materials that don't require a lot of energy or resources to produce. Some products will put that information right on their labels. Instead of buying something you're not going to use very often, see if you can borrow it from someone you know. Cars use up energy and cause pollution. Some ways to reduce the environmental damage caused by cars include carpooling with friends, walking, taking the bus, or riding your bike instead of driving. Start a compost bin. Some people set aside a place in their yard where they can dispose of certain food and plant materials. Over time, the materials will break down through a natural process called decomposition. The compost is good for the soil in your yard and means that less garbage will go to the landfill. You can reduce waste by using a computer! Many newspapers and magazines are online now. Instead of buying the paper versions, you can find them on the Internet. Also remember that you should print out only what you need. Everything you print that you don't really need is a waste of paper. Save energy by turning off lights that you are not using. Save water by turning off the faucet while you brush your teeth. Lots of families receive a large amount of advertisements and other junk mail that they do not want. You can stop the mailings and reduce waste by writing to the following address and requesting that they take your name off of their distribution list: Direct Marketing Association Mail Preference Service P.O. Box 9008 Farmingdale, NY 11735-9008 Reuse Instead of throwing things away, try to find ways to use them again! For example: Bring cloth sacks to the store with you instead of taking home new paper or plastic bags. You can use these sacks again and again. You'll be saving some trees! Plastic containers and reusable lunch bags are great ways to take your lunch to school without creating waste. Coffee cans, shoe boxes, margarine containers, and other types of containers people throw away can be used to store things or can become fun arts and crafts projects. Use your imagination! Don't throw out clothes, toys, furniture, and other things that you don't want anymore. Somebody else can probably use them. You can bring them to a center that collects donations, give them to friends, or even have a yard sale. Use all writing paper on both sides. Use paper grocery bags to make book covers rather than buying new ones. Use silverware and dishes instead of disposable plastic utensils and plates. Store food in reusable plastic containers. Recycle Many of the things we use every day, like paper bags, soda cans, and milk cartons, are made out of materials that can be recycled. Recycled items are put through a process that makes it possible to create new products out of the materials from the old ones. In addition to recycling the things you buy, you can help the environment by buying products that contain recycled materials. Many brands of paper towels, garbage bags, greeting cards, and toilet paper, to name a few examples, will tell you on their labels if they are made from recycled materials. In some towns you can leave your recyclables in bins outside your home, and a truck will come and collect them regularly. Other towns have recycling centers where you can drop off the materials you've collected. Things like paper and plastic grocery bags, and plastic and aluminum cans and bottles can often be brought to the grocery store for recycling. Whatever your system is, it's important to remember to rinse out and sort your recyclables!

"what is jhum cultivation? where it is practiced?" in   Tuition/Class IX-X Tuition

Jhum or Jhoom cultivation is a local name for slash and burn agriculture practiced by the tribal groups in the northeastern states of India like Arunachal Pradesh, Meghalaya, Mizoram and Nagaland and also in the districts of Bangladesh like Khagrachari and Sylhet. This system involves clearing a piece of land by setting fire or clear felling and using the area for growing crops of agricultural importance such as upland rice, vegetables or fruits. After a few cycles, the land loses fertility and a new area is chosen. Most farmers make huts near their land for shelter Jhum cultivation is most practiced on the slopes of hills in thickly forested landscapes. The cultivators cut the treetops to allow sunlight to reach the land. They burn all the trees and grasses for clean and fresh soil. It is believed that this helps to fertilize the land, but can leave it vulnerable to erosion. Later seeds and crops are planted. Plants on the slopes survive the rainy season floods. Looking at all the effects, the government of Mizoram has launched a policy to end Jhum cultivation in the state.
