Carbon Dioxide Greenhouse Effect
1,080 wordsWhile some people believe the earth's climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earth's surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes through the transparent roof and walls an...

Multiple Causation Theory Of Leukemia
1,944 wordsLeukemia is a malignant disease of the bone marrow and blood. It is characterized by the uncontrolled growth of blood cells. The term leukemia has a Latin derivation. Luke means white and heme is blood. Therefore the word leukemia literally means white blood. The common types of leukemia are divided into four major categories: myelogenous and lymphocytic, which can then be divided into acute or chronic. Thus, the four major types of leukemia are acute or chronic myelogenous leukemia and acute or...

Ozone Layer Ultraviolet Rays
1,294 wordsAtmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O 3 gas. The ozone layer is essential to both plant and animal life on earth because it protects the surface from dangerous ultraviolet light. However, industrial and domestic chemicals ...

Stimulated Emission Positively Charged
948 wordsLasers HISTORY OF LASER PRODUCTION The roots of laser mechanism are very modern. In 1900 German physicist Max Planck presented an explanation of why the colors of a glowing hot body may change with temperature. He also proposed discrete quantum theory saying that radiations come in discrete quantities called quanta. Therefore radiations are not only a series of waves but a stream of particles called photons. By 1917, Einstein has outlined the principles underlying the production of laser radiati...

Rise In Sea Level Atmospheric Co 2
1,132 wordsGlobal Warming Debate The global warming is caused by emissions of over 20 gases into the atmosphere. The major contributors are carbon dioxide (CO 2), ozone, methane, nitrous oxide and chlorofluorocarbons (CFCs). Although these gases are produced by many industrial processes, the major source is the burning of fossil fuels in boilers, furnaces and automobile engines. When released into the air in large quantities, these gases cause the earths atmosphere to warm by trapping the suns heat. Infrar...

Big Bang Theory Force Of Gravity
1,630 wordsNot so much a theory of the universe as a simple picture of the planet we call home, the flat-earth model proposed that Earth? s surface was level. Although everyday experience makes this seem a reasonable assumption, direct observation of nature shows the real world isn? t that simple. For instance, when a sailing ship heads into port, the first part that becomes visible is the crow? s-nest, followed by the sails, and then the bow of the ship. If the Earth were flat, the entire ship would come ...

Solid State Lasers Beam Of Light
1,373 wordsA laser (LAY zum) is a device that produces a very narrow beam of light. This is called coherent light. It is formed from producing light at equal wavelengths in phase. The result is a beam of light that does not stray from it? s path. Conventional light bulbs produce incoherent light. This form of light diffuses immediately upon radiation from its source. The size of a laser beam varies greatly. Some lasers produce beams that are small enough to fit 200 beams in an area the size of a pinhead. T...

Stratospheric Ozone Ozone Layer
2,496 wordsThe Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40 km depending on latitude, just above the tropopause. Its existence is crucial for life on earth as we know it, because the ozone layer controls the absorption of a portion of the deadly ultraviolet (UV) rays from the sun. UV-A rays, including wavelengths between 320 and 400 nm, are not affected by ozone. UV-C rays between 200 and 280 nm, are absorbed by the other atmospheric constituents besides...
