Nuclear Weapons A major problem concerning the world today is the disposal of nuclear weapons. With the Cold War, we have seen a massive build up of nuclear weapons, and no, that we are no longer in a state of global warfare, what is to be done with them? As a result of the build-up in nuclear weapons during the cold war the world is now facing major environmental problems trying to deactivate them, and in addition major debate are occurring on the policies of disarmament and deterrence as solut

AIR POLUTION Problem The first thing people see, in the morning, when they walk outside is the sky or the colored sun. Is this world giving us the privilege of seeing the natural colors of the sun through all the layers of pollution within the air (Dinanike 31)? Not only are beautiful sights such as this hidden behind the pollution this world causes everyday, but an increase in diseases, infections and death occurs. What causes pollution? What can we do to prevent it, and get rid of it? Is it fa
Global Warming
Global Warming
Global Warming The greenhouse effect, in environmental science, is a popular term for the effect that certain variable constituents of the Earth's lower atmosphere have on surface temperatures. It has been known since 1896 that Earth has been warmed by a blanket of gasses (This is called the “greenhouse effect.”). The gases--water vapor (H2O), carbon dioxide (CO2), and methane (CH4)--keep ground temperatures at a global average of about 15 degrees C (60 degrees F). Without them the average would

Our Radiant Planet- Depletion of the Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer
Our Radiant Planet- Depletion of the Ozone Layer Ozone is a relatively unstable form of molecular oxygen containing three oxygen atoms produced when upper-atmosphere oxygen molecules are split by ultra violet light. Stratospheric ozone is found in a broad band, extending generally from 15 to 35km above the earth. Although the ozone layer is surprisingly thin, it acts as a protective shield to the earth, as it filters out most of the harmful solar ultraviolet radiation (in particular UV-B) that w

In the form of heat, light from the sun warms the Earth. Light, also, is the single most important factor influencing the growth and development of plants. Photo
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer
The Atmospheric Ozone Layer The stratospheric ozone layer exists at altitudes between about 10 and 40km 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 400nm, are not affected by ozone. UV-C rays between 200 and 280nm, are absorbed by the other atmospheric constituents besides oz

What is meant by the term the greenhouse effect is that the heat from the sun comes into the Earth's atmosphere and cannot get out so becomes trapped.It gets its name because this is very much like a greenhouse.This effect occurs as the incoming short wave radiation is changed when it hits the Earth's surface in

Euthanasia: A Question of Ethics Euthanasia is one of the most acute and uncomfortable contemporary problems in medical ethics. Is Euthanasia Ethical? The case for euthanasia rests on one main fundamental moral principle: mercy. It is not a new issue; euthanasia has been discussed-and practised-in both Eastern and Western cultures from the earliest historical times to the present. But because of medicine's new technological capacities to extend life, the problem is much more pressing than it has

CancerIntroduction According to Mollet, cancer is the second leading cause of death in the United States. Estimates for 1982 indicate that 430,000 Americans will have died of some form of cancer. If national trends continue, some fifty-three million Americans now alive will contract cancer sometime during their lifetime. Of this inverse number, approximately one-half will die of cancer despite a medical effort to cure and prevent cancer (300).Although 45 percent of the detected cases of serious

Hyperkinetic Children Hyperkinetic is just another word for Hyperactive. Hyperactivity describes children who show numerous amounts of inappropriate behaviors in situations that require sustained attention and orderly responding to fairly structured tasks. Humans who are hyperactive tend to be easily distracted, impulsive, inattentive, and easily excited or upset. Hyperactivity in children is manifested by gross motor activity, such as excessive running or climbing. The child is often described

In the 1970’s, natural hazards were an important subject of topical study, as the nature of their impact on human populations and what they valued was increasing in frequency at quite a rapid rate (Burton, Kates, White, 1978). During the 75 years after 1900 the population of the earth increased by a staggering 2.25 billion people. People who needed land on which to live and work. As the population rose people were dispersed in more places and in larger numbers than before. The predominant movem

Each stage in the evolution of human society (the development of farming, domestication of animals, harnessing of wind and water power) increased the average per capita energy use, but it was the Industrial Revolution and th

Nuclear Weapons, explosive devices, designed to release nuclear energy on a large scale, used primarily in military applications. The first atomic bomb (or A-bomb), which was tested on July 16, 1945, at Alamogordo, New Mexico, represented a completely new type of artificial explosive. All explosives prior to that time derived their power from the rapid burning or decomposition of some chemical compound. Such chemical processes release only the energy of the outermost electrons in the atom. See

There are two types of nuclear weapons, fission weapons, which are known as atomic weapons and thermonuclear weapons, which are commonly called hydrogen or fusion weapons. In fission weapons, matter is changed into energy when uranium isotopes U-235, U-238, or the plutonium isotope Pu-239 are split. Once the nucleus splits, the little matter is ma

The Roles of Predator Avoidance and Light in the Diel Vertical Migration of Zooplankton Almost all zooplankton species undergo diel vertical migration (DVM) at some time in their life cycle. The most commonly observed type of DVM is a nocturnal pattern which consists of a single daily ascent with minimum depth reached between sunset and sunrise and maximum depth attained during the day (Forward and Hettler 1992). Migrating animals spend the day in deep waters and stay near the surface at night.

To give the Allies an edge, British and American scientists developed radar technology to see for hundreds of miles, even at night. The research that went into improving radar helped set the stage for post-war research into the transistor. 1940s radar relied on a semiconductor crystal, or rectifier.
