Iron
Number of Words: 1056 / Number of Pages: 4
... oxide,
commonly known as rust. (Encarta, 1996)
Iron is formed in shallow seas. It comes out of the water and collects
on the sea floor. This creates an underwater deposit. This process occurs over
billions of years. Through plate movement the whole sea floor is eventually
moved up out of the water. Once out of the water, the iron has formed a land
deposit. The biggest iron deposit in the United States is in the Great Lakes.
Northern Minnesota is often called the Iron Range. There are two ways iron
deposits are located. In the first method special machines that detects the
iron's magnetis ...

Into The Depths Of A Black Hole
Number of Words: 1311 / Number of Pages: 5
... energy of the two gas clouds. This energy produced is so great
when it first collides, that a nuclear reaction occurs and the gases within
the star start to burn continuously. The Hydrogen gas is usually the first
type of gas consumed in a star and then other gas elements such as Carbon,
Oxygen, and Helium are consumed.
This chain reaction fuels the star for millions or billions of years
depending upon the amount of gases there are.
The star manages to avoid collapsing at this point because of the
equilibrium achieved by itself. The gravitational pull from the core of
the star is equal ...

Death Of A Planet

... monoxide and
nitrogen oxide. The first reduces the flow of oxygen to the bloodstream, and
could harm people with heart disease. Nitrogen oxide is formed when a car
engine gets hot. It contains chemicals that aid in the formation of ground
level ozone as well as acid rain (2 factsheet, OMS-5). Acid rain destroys the
outsides of buildings, statues, etc. Acid rain can also contaminate drinking
water, damage vegetation, and destroy sealife. These two pollutants are two of
the most dangerous pollutants released through car exhaust. If these two
pollutants were cut down just a little bit our plane ...

Differences And Effects Of Natural And Synthetic Fertilizers
Number of Words: 679 / Number of Pages: 3
... inspection, to detect such things as the pH of the soil.
A soil with a pH above 7.0 is called an alkaline soil, and will commonly kill
plants. Mineral content, as mentioned above, is also a concern, and must be
clearly monitored. After inspection, it is common for minor organic materials
outside fertilizers to be applied, such as peat moss, ground bark, or leaf mold.
It is after these steps that fertilization must occur, leading to a debate which
has plagued gardeners and scientists alike: organic or chemical?
Fertilizers, in both natural and synthetic breeds, are carriers of the
primary and ...

How Low Self-esteem Effects Anorexia
Number of Words: 1288 / Number of Pages: 5
... to gain the appropriate levels of
self-esteem.
Anorexia is a big issue in society today.
Girls and boys are developing anorexic symptoms as
young as age five. While anorexia can be detected
in boys, girls, men, and/or women of all ages, “the
most common ages of onset [remains] between
thirteen and twenty-two.”(Levenkron,1)
Anorexia nervosa is an eating disorder. People
who develop anorexia are usually “afraid of
becoming obese and [have] such a distorted image of
[their] body, that [they] steadfastly [refuse] to
eat even when...hungry.”(Mathews, 29) ...

Global Warming 2 --

... also known as Chlorofluorocarbons, hydrofluorocarbons, and perfluorocarbons. These gases are generated a number of human activities such as fossil fuel combustion, waste disposal in landfills, the
use of a refrigerator, numerous agricultural and industrial activities, and the cutting down of numerous forests.
These human practices have already changed the chemical make up of the atmosphere. Between the pre-industrial times and today, we have seen the concentration of carbon dioxide rise 30% in some regions, in particular the northern hemisphere, human practices have increased concentrations of aero ...

... animals is ethical or even moral. Also there has been much discussion as to whether or not the benefits of cloning outweigh the dangers.
WHAT ARE THE BENEFITS IN CLONING RESEARCH?
There is no doubt that Dr. Wilmut's new discoveries have brought an uproar of excitement between not only the scientific community, but the general public as well. Groups such as farmers, surgeons and even environmentalists have shown various interests in cloning research.
The farming community has expressed much intrigue in cloning for the purpose of being able to reproduce copies of their best animals. For examp ...

Atmosphere Crisis
Number of Words: 646 / Number of Pages: 3
... the predicted result of the greenhouse effect, created by so-called greenhouse gases, such as carbon dioxide and methane, in the atmosphere. The increase in these gases is thought to be caused by industrialization, especially by the use of fossil fuels such as coal and oil. These gases act much like the glass in the greenhouse: They let sunlight in and keep the heat from escaping. As these gases increase in our atmosphere, concern has grown that temperatures will increase around the globe, just as in the inside of a greenhouse. Global warming will have wide spread impacts on health, economics, politics ...

Cold Fusion
Number of Words: 954 / Number of Pages: 4
... Some claim it is merely a chemical reaction not yet understood, while others are convinced it is a nuclear reaction.
One example is a cell which used .04 grams of metal hydride. It produced 86 megajoules over a two month period. A similar chemical reaction would have required 2,000 grams of chemicals to produce the same amount of energy. Another interesting point regarding this cell was the fact it had to be deliberately shut down. There was no sign of the reaction tapering off.
The skepticism regarding stems from two separate studies, one done by MIT, and the other by the Energy Resources ...
