Alternate Energy Sources
535 Words - 2 Pages.... the plasma molecules to be heated up around temperatures of 5,000,000 C%. The kinetic energy is then extracted by passing through a magnetic field. This produces a strong voltage. The only disadvantages to this power source is the lack of knowledge we have for it. Hopefully, within time, we will learn about this new energy source so we can use it to power the future.
Fusion Power
Fusion Power is probably the biggest known Alternate Energy Resource. Fusion is the joining of the nuclei of two atoms to form the nucleus of a heavier element. It occurs mostly with hydrogen and other light elements. Fusion reactions, also called thermonuclear reactions, release a great d ....

David Suzuki's A Planet For The Taking
944 Words - 4 Pages.... and is followed by
more detailed explanations. The general opinions in the beginning are well-
chosen considering the audience. Suzuki's tone is evident when he states "We
have both a sense of the importance of the wilderness and space in our culture
and an attitude that it is limitless and therefore we needn't worry." These
words suggest that we are willing to reap the rewards of our vast resources but
we fail to see the harm that we are doing, and will continue to do if we do not
stop these actions.
Although his approach for explaining his beliefs changes, Suzuki's tone
of great concern remains consistent throughout the essay. After his views are
presented, ....

Earthquakes

Aristotle believed that "mild were caused by wind escaping from caves within the bowels of the earth and severe shocks were by gales that found their way into great subterranean caverns" (Matthys 87). However, with modern technology we found that what actually causes is tectonic plates which on average move only two inches per year they are driven by convection currents which is the upward movement of heated particles rising from the earth's molten core. As the plates are driven against each other one will try to and eventually will slip underneath the other. When plates move quickly an earthquake is the result.
Before the availability ....

Finding Mass Using The Inertial Balance
575 Words - 3 Pages.... by measuring the oscillation period and comparing it to a known mass period. The relationship m1=m2T12/T22 was discovered.
Objective: After completing the experiment, we will be able to find the mass of objects using an inertial balance and compare them to accepted measures.
Materials: C-clamps, inertial scale, a watch with a second hand, and a triple beam balance.
Procedure: 1) The class will measure the period of oscillation of their balance pans when they are empty. The accepted period will be the average of the class. To find the period, you will measure the amount of time it takes for your balance to complete 20 oscillations. The period (T) will be compu ....

Human Evolution In Africa
829 Words - 4 Pages.... warmer than it now is. As time went on, the small mammal had spread throughout Eurasia. All of Eurasia then was covered in tropical forests. Primates evolved in what is now the Indian Subcontinent.
From their placement in India, then still lowland, primates spread throughout the world once more. Some returned to North America, only to be wiped out by rodents already living there. Others spread to Europe and the Middle East.
By this time, Africa had just split from marsupial overrun Gondwanaland. About a million years later it reached the Middle East, and primates moved in. By now the world had cooled enough that the primates in Europe had been decimated to near ext ....

Gold And Its Uses
2573 Words - 10 Pages.... current in temperatures varying from -55° to +200° centigrade." (Gold Institute) Gold is the most ductile of all metals, allowing it to be drawn out into tiny wires or threads without breaking. Consequently, a single ounce of gold can be drawn into a wire five miles long. Gold's malleability is also unparalleled. It can be shaped or extended into extraordinarily thin sheets. For example, one ounce of gold can be hammered into a 100 square foot sheet.
Gold is the most reflective and least absorptive material of infrared (or heat) energy. High purity gold reflects up to 99% of infrared rays. Gold is also an excellent conductor of thermal energy or heat. Since many el ....

The Problems With Acid Rain
1834 Words - 7 Pages.... and cost of properly disposing of these products they are often emitted into the atmosphere with little or no treatment.
The term was first considered to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early.
At the beginning of the 20th century most rivers/lakes lik ....

The Problem Of Global Warming
457 Words - 2 Pages.... Every car produces enough gases from its exhaust
into the atmosphere that takes a mature tree to clean in about five years.
Trees keep the air clean for the environment by taking the gases in and produces
oxygen out of it. By cutting down the trees we are allowing for more of the
carbon to be exposed into the atmosphere.
Another factor that most people would not consider in the raising of
global warming is the excrement of cows. Cows produces tons of carbon that does
not all get treated for, and is in the top five for highest amounts of carbon
produced per year. This is another factor that somehow has to be dealt with.
All of these causes of global warming have been ....
