Geothermal Energy
Words: 4686 / Pages: 18 .... that we must take into consideration before can be a possibility for a human resource. I will be discussing some of these issues, questions, and problems. In the beginning when the solar system was young, the earth was still forming, things were very different. A great mass of elements swirled around a dense core in the middle. As time went on the accumulation elements with similar physical properties into hot bodies caused a slow formation of a crystalline barrier around the denser core. Hot bodies consisting of iron were attracted to the core with greater force because they were more dense. These hot bodies sunk into and became part of the cons .....

Earth's Climate And Seasons: ‘How Do They Relate?’
Words: 393 / Pages: 2 .... If you would take all ball, and shine a flashlight on it, there is no way possible to get the light to spread evenly over the entire ball. This is just like Earth and the sun. The earth’s shape makes the light amount about even, for example, at 40%S and 40%N latitude because the rays sort of fan out from the equator. While the earth is revolving around the sun, it is also rotating on it’s own axis. One full rotation equals one day or twenty- four hours. At the middle of the day, noon, the sun is as direct as it can be, and this is also the hottest time of the day. But, when Earth makes one half turn, it changes to night when all of the .....

Atmospheric Circulation And More
Words: 685 / Pages: 3 .... equator where the process is
repeated. Another major contributing factor to the circulation of the air
is due to the subtropical highs. These highs like the ITCZ migrate during
the different seasons.
The idealized belt model is a great representation of the general
circulation of the atmosphere. The equatorial belt of variable winds and
calms ranges from 5 degrees north to 5 degrees south. This wind belt is
characterized by weak winds and low pressure from the inter tropical
convergence zone. As you go further north or south you encounter the
Hadley Cells. Hadley cell circulation is caused by the movement of high .....

The Dust-Cloud Hypothesis
Words: 318 / Pages: 2 .... and
probably weighed 500 times as much.
The large body of dust and gas forming the sun collapsed rapidly to a much
smaller size. The pressure that resulted from the collapse caused the sun
to become very hot and to glow brightly.
The newly born sun began to heat up the swirling eddy of gas and dust that
was to become the earth. The gas expanded, and some of it flowed away into
space. The dust that remained behind then collected together because of
gravity. Although the shrinking earth generated a lot of heat, most of
this heat was lost into space. Therefore, the original earth was most
likely solid, not molten.
This hypothesis was developed .....

Essay On Evolution
Words: 913 / Pages: 4 .... the gene pool of the previous generation. If it is small, its
gene pool may not be accurately represented in the next generation due to
sampling error. Genetic drift usually occurs in small populations that contain
less than 100 individuals, but in large populations drift may have no
significant effect on the population. Another mechanism is gene flow which is
when a population may gain or lose alleles by the migration of fertile
individuals between populations. This may cause the allele frequencies in a gene
pool to change and allow the organism to evolve. The most obvious mechanism
would have to be mutation that arises in the gene pool of a populat .....

Nuclear Energy
Words: 1733 / Pages: 7 .... is fueled
by uranium isotopes. These isotopes are highly radioactive. The isotope
catches the fast moving neutrons created by the splitting atoms, it repels the
slower moving protons and electrons, then gathers the neutrons and pulls them
inward. While all these atoms are flying about they smash together then split
many of many times, this is when the reactor grabs and pulls in the frictional
energy to be processed into electrical watts.
This usually causes heat or thermal energy, this must be removed by some
kind of a coolant. Most power plants use water or another type of liquid based
formula. these coolants are always base related, never acid .....

Mononucleosis
Words: 1043 / Pages: 4 .... is known to be caused by the Epstein_Barr virus (EBV), which can be passed by coughing, sneezing or saliva transfer, where it gets it’s popular name, the “kissing disease”. Much like chicken pox, most people don’t receive a second time in their life, but it can happen. Relapses can occur, but are fairly uncommon. Although you can receive the disease very easily, is not highly contagious, according to the majority of sources.
Symptoms
There are many symptoms associated with infectious , but the symptoms all depend on the individual. The more common symptoms are fatigue, sore throat, swelling of the lymph nodes and m .....

Concept Of Species
Words: 1248 / Pages: 5 .... isolated from
others) that occupies a specific niche in nature
The BSC is greatly accepted amongst vertebrate zoologists & entomologists.
Two reasons account for this .Firstly these are the groups that the
authors of the BSC worked with. (Mayr is an ornithologist & Dobzhansky has
worked mainly with Drosophila). More importantly Sexual reproduction is
the predominate form of reproduction in these groups. It is not
coincidental that the BSC is less widely used amongst botanists.
Terrestrial plants exhibit much more greater diversity in their mode of
reproduction than vertebrates and insects.
There has been many criticisms of the BSC in it .....

Alternative Medicine
Words: 4283 / Pages: 16 .... costs provide the all important profit margin, the life
blood of the insurance industry. By not providing coverage for
the billion dollar industry of alternative treatments, insurance
companies are keeping the cost of the premiums down but at the
same time not allowing their customers to use complementary
treatments such as chiropractic to prevent or cure illness. The
more rigid and restrictive the policy provisos, the more
assurance for the companies that they will maximize their bottom
lines. Therefore, patients of alternative therapies as well as
doctors must show that such unconventional treatment provides
relief and prevention of ill .....

Cd Roms
Words: 1257 / Pages: 5 .... drive it looks like large CD:ROM , but this one is magnetic. If you open one up it will look like egular record player. The needle is what writes the information onto the hard drive. The needle writes by the magnetic force that pushes it down on to the disk. Once it is on the hard drive , whenever you turn on your computer the information is always there for you when you need it.
A CD:ROM looks like a music compact disk , but they are not that much alike. First a CD:ROM has a lot more information than a regular compact disk. A CD:ROM has audio as well as visual information. Second a CD:ROM stores more data in it. Third if you put a CD:ROM in a c .....
