Parts Of It To Rise Slowly Killing Atmosphere
431 wordsThe atmosphere is a forever moving shell of gas that surrounds our planet, harming and protecting life on earth at the same time. Its turbulence is caused by the uneven distribution of the suns energy over its surface, causing parts of it to rise and the others to fall. Thus creating winds and carrying moisture from one place to another. The atmosphere is among the most unpredictable aspects of nature. It protects life on the surface by block from it the powerful radiation and most asteroids fro...

000 Short Tons Ways To Detect Copper
699 wordsBlake Adams Period 3 Grade 8 2 / 5 / 97 Copper is a mineral. it is not a plant or a animal. Copper is a metallic metal. It can never be broken down into different substances by normal chemical means. Copper was one of the first metals known to humans. People liked it because in it's native condition, it could easily be beaten into weapons or tools. Copper has been one of the most useful metals for over 5000 years. Copper was probably used around 8000 B. C by people living along the Tigris and Eu...

Effects Of Global Warming Polar Bears
1,306 wordsEffects of Global Warming On Polar Bears and Polar Seals Introduction Polar bears depend on polar seals as a source of food in the polar region. Polar bears hunt polar seals before winter comes, so they can get all the proteins and fats they need in order to survive. Global warming is increasing the melt of ice in the Arctic region. As a result, polar seals will not be able to survive and face the environmental changes including climate. Therefore, polar bears will be threatened by starvation an...

Permian Extinction Mass Extinction
537 wordsThe Mother of All Extinctions The article deals with the question that has been argued about by biologists and geologists for many years now. In the history of Earth, there were a number of mass extinction events that left their track in the geological record. This particular article addresses the largest one that ever happened, The Permian extinction which took place about 250 million years ago and destroyed 90 % of all living forms on Earth. Until recent time, the Permian extinction was not so...

Carbon Dioxide Emissions Global Climate Change
772 wordsBush Wont Regulate Carbon Dioxide Updated 7: 30 PM ET March 13, 2001 By SCOTT LINDLAW, Associated Press Writer WASHINGTON (AP) Backing off a campaign pledge, President Bush told Congress Tuesday he will not regulate carbon dioxide emissions from power plants. The decision, outlined in a letter sent to a Republican senator, came after furious lobbying from the coal industry. It was a blow to conservationists who see curbing emissions of such greenhouse gases as key to reducing global warming. The...

Greenhouse Gases Ultraviolet Radiation
421 wordsDiscovery of the hole in the ozone layer showed that human activity has a major impact on Earth. The destruction of ozone in the stratosphere high above the planets surface has been brought about as the result of the widespread use of chemicals, which under normal conditions are chemically inert and harmless. Ozone occurs at all levels in the atmosphere, but most of it is found in the stratosphere, between about 15 - 50 kilometres above the Earths surface. Even there it occurs in minute concentr...

Ozone Layer Ultraviolet Rays
962 wordsThe Problem The atmospheric ozone layer protects all living things from the harmful effects of the Sun. In recent years however, much damage has been caused to the ozone layer, causing it to decrease in size. The depletion of the ozone layer has and will continue to have many detrimental effects on all living things on this planet. A thinner layer will allow more of the suns ultraviolet radiation to reach the Earths surface. In particular, it will be the increase of UV-B rays which will have the...

Infinite Regress God Exists
1,002 wordsAquinas second proof that God exists, the proof from efficient cause, is summarized in the following: there exists things that are caused, nothing can be the cause of itself, there cannot be an infinite regress of causes, there fore, God exists. The proof of Aquinas s is a cosmological kind, basing the fact the if anything exist; an absolute necessary being must also exist. I agree with Aquinas that God is the uncaused first cause, but from a situation that was discussed in class a few weeks ago...

Million Tons Energy Consumption
369 wordsENERGY CONSUMPTION The United States of America uses more than one fifth of the worlds resources. Energy consumption doubled between 1952 and 1972 and although consumption has slowed it continues to rise at an alarming rate. In the 1940 s the U. S. A exported fuel but by 1952 it was importing large amounts of oil and coal. Since 1981 the cost of fuel imports has been over 75 billion a year. The U. S. A is now being forced to mine oil and natural gases in places like deep-sea basins. Only 6 % of ...

Million Years Ago Millions Of Years
923 wordsReptiles Enjoyed Warm Arctic (Global Warming) An article written by ABC News writer Kenneth Chang discusses the change in climate of the arctic from ninety million years ago. Seven hundred miles from the North Pole, lies an island called Axel Heiberg, a barren land that scientists have dug up fossil bones of a cold-blooded reptile known as a champsosaur. How does this happen in an arctic, freezing land? How does a reptile that needs the warmth of the sun to survive, live in a frigid climate? Wel...

Greenhouse Gas Emissions Earths Surface
297 wordsThis Greenhouse Effect Greenhouse Effect This effect is the result of certain atmospheric gases letting sunlight through to the earths surface, while not letting energy radiated outward from the earths surface. This results in a net buildup of solar energy in the Earths atmosphere, because the flow in is greater than the flow outwards. The chemicals that are most significantly involved in this effect are chlorofluorocarbons (CFCs), hydrogenated chlorofluorocarbons (HCFCs), nitrous oxide (N 2 O),...

Greenhouse Effect Is Caused Effect Is Caused Rays
310 wordsThe Greenhouse Effect Our world is suffering, and it is suffering from something people call the Greenhouse effect. The greenhouse effect is caused by humans over pollution of the earth. If we do not stop this soon the earth will die. We have caused this over many years of over industrialization in this growing world. We think that bigger is better, so we make vehicles bigger and better, and we make pretty much everything else bigger as well. So we make larger factories to build these larger thi...

546 wordsThe Biggest Environmental Problem The environmental problem that must be considered as the biggest, is the Global Warming. Temperature is slowly increasing all over the world. To understand this better it is also important to explain the greenhouse effect. The greenhouse effect in a summary: Sunlight radiates from the sun, through space, to earths atmosphere. The sunlight enters the atmosphere and hits the earth. Some of it turns to heat energy in the form of infrared light. The heat absorbs by ...

Physical Science 1 Page
602 wordsBefore we look at insulation we must see how thermal energy moves. There are three ways it moves. The first is by conduction. Conduction is the transfer of energy by direct contact of particles. Heat spreads through out an object till the object is the same all the way around. (Physical Science section 6. 1, page 1) This happens because all particles vibrate unless in an absolute zero situation. These more violently moving particles hit each other. Eventually these particles will vibrate at the ...

Stimulated Emission Nobel Prize
1,216 wordsThe Wonderful World of Lasers Laser stands for Light Amplification by the Stimulated Emission of Radiation. Lasers work by producing an intense beam of bright light that travels in one direction. The laser has the unique ability to produce one specific color or wavelength of light, which can be varied in its intensity and pulse duration. The newest laser systems have become remarkably precise and selective, allowing treatment results and safety levels not previously available. All lasers contain...

Nuclear Reactions Mechanical Energy
511 wordsHave you ever wondered how a jet aircraft lifts its tremendous weight off the ground, or what gives a runner the stamina to reach the finish line in a race? In order to answer all these questions we must talk about the transformation of one sort of energy into another. The jet aircraft gets its power from jet turbines. These powerful jet engines create a high-pressure stream of very hot gases that push the aircraft forward as they leave the engine. This is an example of heat being transformed in...
