... of their
precipitation.
Although numerous tropical storms develop each year, only a few
reach hurricane status, which by international agreement requires wind
speeds in excess of 119 kilometers per hour and a rotary circulation.
Hurricanes average 600 kilometers in diameter, and often extend 12,000
meters above the ocean surface. From the outer edge of the hurricane to
the center the barometric pressure has on occasion dropped 60 millibars,
from 1010 to 950 millibars. The lowest pressure ever recorded in the
United States was 892.31 millibars.
The steep pressure generates the rapid, inward spir ...

A Fabulous Analysis Of The Flamboyantly Gay
Number of Words: 605 / Number of Pages: 3
... As is the case in any good romance movie, the onlooker with bottled emotions waits until the end to release everything, dramatically and emotionally releasing all her pressurized tensions. Sure, Hollywood is not the best place to get your life morals, but a lesson really can be learned here, and the same lesson can be applied to the big question at hand.
“Why does he act so gay?” By now you may be realizing where I am going with this. If you can put two and two together to make four, you can put the above concept together with the question to get the answer. With the wavering inconsisten ...

... feverish and anemic, lost their appetites, and had hemorrhages. The experimenters compared their results to those experiments conducted at the University of Utah and the Argonne National Laboratory in which beagles were injected with Strontium 90. They concluded that the dose needed to produce “early death” in fifty percent of the sample group differed from test to test because the dogs injected with Strontium 90 retain more of the radioactive substance than dogs forced to inhale it. Also, at the University of Rochester School of Medicine a group of experimenters put fifty beagles in wooden boxes and ...

... and Morris W. Travers discovered it in 1898. Its uses include electric signs, lamps, and lasers.
Argon is the most abundant and most used noble on earth. Sir Walter Ramsey discovered it by Lord Rayleigh and in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and fluorescent tubes. It is also used a lot in industry.
Krypton a very rare noble was discovered by Sir Walter Ramsey and by Morris W. Travers. Traces of it are found in natural gas, hot springs and volcanoes but most of it is in the atmosphere. I ...

... natural disasters or means. This ten percent of all sulfur dioxide emission comes from volcanoes, sea spray, plankton, and rotting vegetation.
The oxides of nitrogen are by-products of firing processes of extreme high temperatures, for example: automobiles, and utility plants; and in chemical industries, for example: fertilizer production, etc. Also, natural processes such as bacterial action in soil, forest fires, volcanic action, and lightning make up five percent of nitrogen oxide emission. Transportation makes up 43 percent, and 32 percent belongs to industrial combustion.
There are a numbe ...

Water Pollution
Number of Words: 1517 / Number of Pages: 6
... dolphins often get tangled in the plastic six-pack rings, fishing lines, and net that humans discard into the ocean waters. Once entangled, they are unable to free themselves which can cause deep cuts, starvation, and drowning. Many ocean mammals have died as a result of ingesting these plastic items. In 1985, a sperm whale beached itself on a New Jersey shore; a mylar balloon was lodged in its stomach, and three feet of ribbon in its intestines. Most plastics take hundreds of years to break down. Many of the discarded items will sink to the ocean floor where they will combine with sediments, thus pr ...

... 60°F. But, problems may happen when the amount of
greenhouse gases increases.
Since the beginning of the industrial revolution, great amounts of carbon dioxide have increased nearly 30%, methane concentrations have almost doubled, and nitrous oxide concentrations have risen about 15%. These increases have made the heat-trapping worse in the earth's atmosphere. Sulfate aerosols, a common air pollutant, cool the atmosphere by reflecting light back into space, but, sulfates do not live long in the atmosphere.
Why are greenhouse gas concentrations increasing? Most scientists believe t ...
