ADVERTISEMENT

            There are many reason as for both sides of questions. Should we have printed advertisement? Many people have strong views and feel that ads are nothing more than useless junk mail, while other people feel there are important source of information.

            Here are some reasons why we should have advertisement newspaper and magazine. One reason is ads give us information about what is available. Looking at ads we can find out what is on sale and what is new in the market. Another reason is that ads promote business. When shop owners compete against each other the buyer saves money, more people come to their shops and they sell more goods.

            On the other hand, some people argue ads should not be put in newspaper and magazine for these various reasons. Firstly, ads cost the shop keepers a lot of money to print onto paper. Also some people don’t like finding junk mail on their letter boxes. People may also find the ads nor very interesting. Ads also influence people to buy items they don’t need and can’t really afford. Ads use up a lot of space and a lot of effort has to be made to make the ads eye catching. Ads also take up a lot of room in the papers and I don’t think I find some of them interesting.

            In summary, although ads provide people with information, they cost a lot of money to print.

GEYSER

            A geyser is the result of underground water under the combined conditions of high temperatures and increased pressure beneath the surface of the earth.

            Since temperature rises approximately 1 degree F for every sixty feet under the earth’s surface, and pressure increases with depth, water that seeps down in cracks and fissures until it reaches very hot rocks in the earth’ interior becomes heated to temperature in excess of 290 degree F. Because  of the greater pressure, it shoots out of the surface in the form of steam and hot water. The result is a geyser. In order to function, then, a geyser must have a source of heat, reservoir where water can be stored until the temperature rises to an unstable point, an opening through which the hot water and steam can escape and underground channels for re-supplying water after an eruption.

            Favorable conditions for geyser exits in regions of the world : New Zealand, Iceland, and the Yellowstone National Park area of the United States. The most famous geyser in the world is Old Faithful in Yellow Park. Old Faithful erupts almost every hour, rising to a height of 125 to 170 feet and expelling more than ten thousand gallons during each eruption.
