Gonorrhea
Gonorrhea Gonorrhea Gonorrhea is a sexually transmitted disease. The disease is caused by the bacterium Neisseria gonorrhea that is a member of the family Neisseriaceae. The majority of the organisms belonging to this family are non-pathogenic or commensals, however, gonorrhea is always pathogenic. Bacteria are introduced during sexual contact. It attacks the urethra in males, the cervix (not the vagina) in females, and the throat. Because symptoms are not always present, y...

Global warming a serious threat Is global warming a serious threat? As human technology has been developed by scientists and researchers, we not only get a comfort in living throughout our life but it also helps people to find more jobs and less popery. However, on the other hand, there are some increasing problems on our planet earth due to human activities. They increased the global temperature about 0.5F to 1.1F (0.3~0.6C) since the last half of the 19th century (Global warming 1)...
Global warming and the greenhouse effect
Global warming and the greenhouse effect The Greenhouse Effect and Global Warming Recently, global warming has moved to a serious scientific issue. Because sunlight is constantly falling on the earth, the law of physics say that the planet has to radiate the same amount of energy back into space. Infrared radiation is sent out by the earth through the atmosphere, where molecules (carbon dioxide) hold outgoing radiation for a while, warming the surface.1 The molecules are kind of lik...

Global warming extended definition essay Global Warming Extended Definition Essay The importance of the stratospheric ozone layer, which filters out most of the sun's harmful ultraviolet radiation, in protecting the Earth's surface from the harmful effects of solar ultraviolet radiation has been recognized for many decades. It was not until the early 1970s, however, that scientists began to actually grasp the fact that even relatively small decreases in the stratospheric ozone concentr...
Global warming is it getting warmer
Global warming--is it getting warmer Greenhouse Effect: Is it Getting Warmer? By definition, the greenhouse effect is a term for the role the atmosphere plays in insulating and warming the earth's surface. In modern society, this is the term for something better known as global warming. The earth’s climate is predicted to change drastically in the next century due to human activity. As the population of the world increases, so does the anount of greenhouse gasses produced. Thes...
Global warming 3
Global warming 3 - Global Warming What is global warming, and how is it affecting the Earth and it’s inhabitants? Global Warming is sometimes referred to as the greenhouse effect. The greenhouse effect is the absorption of energy radiated from the Earth’s surface by carbon dioxide and other gases in the atmosphere, causing the atmosphere to become warmer. The greenhouse effect is what is causing the temperature on the Earth to rise, and creating many problems that will begin t...

Few, if any, trends are more important to our future than climate change caused by human activities. Sci...
Global warming 2
Global warming 2 - Global Warming I have chosen to speak about Global warming because it is a major scientific issue in the media. Problems facing the environment today are vast and diverse. Destruction of the world's rain forests, the depletion of the ozone layer, air pollution, water pollution, chemical pollution and global warming are just some of the problems that will reach dangerous proportions in the coming decades. The three aspects of global warming I will discuss a...
Global warming 2
Global warming 2 Like the glass in a greenhouse, certain gases that occur naturally in the atmosphere tend to trap the sun's heat. This natural "greenhouse effect" helps keep the Earth's average temperature at a comfortable 59� Fahrenheit. Without these greenhouse gases, the Earth would be about 0� F, like a deep- frozen snowball. The earth's climate is predicted to change because human's are changing the chemical composition of the atmosphere by the buildup of greenhouse ga...
Global warming 3
Global warming 3 -- Global warming (After a lot of reading and hunting around on the net, I found a great deal of information on this topic. I had never really researched on it before so wanted to make sure that calculations agreed from report to report. Most of them did so I will base my answer on these different reports. This subject is extremely interesting, scary and a bit of a shock as to how much we have abused and taken advantage of this Earth. Though progress as far as technolo...
Global Warning
Global Warning As the world's expanding population burns large quantities of fossil fuels and simultaneously cuts down large expanses of forests worldwide, the concentrations of CO2 and other greenhouse gases are building up in the atmosphere. "The green house effect is the (imperfect) analogy used to explain the atmospheric phenomenon that keeps our planet warm enough to sustain life." There is mounting evidence that this shift in Earth's atmosphere will lead to global changes and potential...
Global warming
Global warming ------ The earth’s climate is predicted to change because human actions are altering the chemical composition of the atmosphere through the increase of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. Global warming is a problem that everybody should be aware and concerned about. It affects you no matter how or where you live, it could cause mass destruction and chaos. Global warming is the rise in the earth’s average temperature resulting f...
Global warming
Global warming -. GLOBAL WARMING In 1992 the United States and nations from around the world met at the United Nations Earth Summit in Rio and agreed to voluntarily reduce greenhouse gas emissions to 1990 levels by the year 2000. The Rio Treaty was not legally binding and, because reducing emissions would likely cause great economic damage, many nations will not meet the goal. Representatives from around the world met again in December of 1997 at a conference in Kyoto to sign a revised ...
Global warming 2
Global warming 2 -- Global Warming Global Warming, aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 steps in the Greenhouse effect. 1-Sunlight radiates from the sun, through space, to Earth's atmosphere. 2- The sunlight enters the atmosphere and hits Earth. Some of it turns into heat energy in the form of infrared light. The heat gets absorbed by surrounding air and land, which in turn makes it warm. 3- Infrar...

Gibbons
Gibbons I. Introduction Apes have 13 species of large, highly intelligent primates, including Chimpanzees, Gorillas, Gibbons, and Orangutans. Apes are sometimes confused with Monkeys, but unlike their smaller primate counterparts, apes do not have tails and their arms are usually longer than their legs. Apes live in tropical woodlands and forests of Africa and Asia. Despite sharing similar habitats, different ape species show striking differences in behaviors and ways of life. At ...

Give an overview of life through the tertiary, in relation t The tertiary consisted of two main epochs. The Paleocene, the Eocene and the Oligocene, which make up the Paleogene; and the Miocene and Pliocene, which make up the Neogene. The close of the Cretaceous Period marked a major transition in Earth’s history. Ammonoids and marine reptiles disappeared from the sea. Marine taxa that persist as familiar inhabitants of modern ocean, among them bottom dwelling molluscs. On the land, ...

Geology fo mars
Geology fo mars Geology of Mars by Luke Justis Mars is the planet that is the closest geologically to our own. Still we know little about the planet. All the information that we have is from what we see. We can speculate about the geology of the planet but we will never know for sure what the planet is really made of until we physicallygo there. The information is all from NASA sites or NASA related sites. Mars’ red color leads us to believe that the pl...
Geoloy of mars
Geoloy of mars Mars is the fourth furthest away from the sun and is recognized by its reddish color. Mars is also very much like the Earth. " More than any other planet in the solar system, Mars has characteristics that make it an Earth-like world "(Grolier, 1992). One thing that is very similar to Earth is the rotation period. Mars rotation period is only thirty seven minutes longer than the Earth's. This would explain why Mars has significant seasonal changes just as Earth does. It is beli...

Geothermal energy 2
Geothermal energy 2 I. Overview of Geothermal Energy Geothermal energy (from the Greek words geo [earth] and therme [heat], thus 'earth heat' energy) is a domestic energy resource with cost, reliability, and environmental advantages over conventional energy sources. Energy from this source comes from the renewable source of heat from deep in the Earth (diagram: A). Heat is brought up to near the surface by thermal conduction (diagram: B) and magma. This heat heats ground water to for...
