Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding1. There are, of course, more definitions of science. An ecologist observing the territorial behaviors of bluebirds and a geologist examining the distribution of fossils in an outcrop are both scientists making observations in order to find patterns in natural phenomena.
When one starts a car or burns wood, the last thought on their mind is the consequences to these actions. Unfortunately, the daily dangers to earth are not widely know.
Due to the constant change of society, this planet must cope with various problems. One of the most important ecological structures is the ozone layer.
The same shield that protects us from the sun"s deadly radiation, can also act as a Earth science atmosphere essay essay engulfing us in heat. This situation is know as the greenhouse effect. What is the greenhouse effect, what causes it, and what can be done to control it? The problem of global warming has been around for some time now.
Though not until recently has it become a priority.
So important, that figures such as Vice President Al Gore have spoken out. Many are realizing that the greenhouse effect is not something to be put aside, yet rather something to be worked on and studied.
Ways must be found to lessen the threat of this growing crisis. If this effect were to continue and grow, the earth"s population would be exposed to serious threats. Carbon dioxide is essential for plants who use it for photosynthesis, yet too much can lead to serious threats.
The problem lies in the disruption of the balance between how much carbon dioxide plants intake, and what our population produces.
If this natural filtering process is unbalanced, the atmosphere will receive too much carbon dioxide and other greenhouse gases. Once these gases form in the atmosphere, they act as barriers trapping in heat and warming the earth.
This process is not new. In fact, without the greenhouse effect, the average surface temperature of the earth would be about 59 Fahrenheit degrees lower than it is today. The greenhouse effect received its name because the atmosphere of the earth acts much like the glass roof on a greenhouse.
Sunlight enters the greenhouse through the glass as it heats up the plants. Then, the warmth is trapped as the glass slows the withdraw of heat. Similarly, the earth"s atmosphere lets most of the sun"s light enter and heat the surface. The earth then sends this energy, called Infrared Radiation, back into the atmosphere showed in the diagram on page 7.
This is when the actual effect takes place. Not all of the Infrared Radiation is sent freely into space. Certain gases in the atmosphere absorb it and send it back toward earth. Such gases are Carbon Dioxide, Ozone, and water vapor.
As stated earlier, this process becoming more important. Due to the burning of fossil fuels such as coal, oil, and natural gas, carbon dioxide is increasing thus increasing the amplitude of the greenhouse effect.
The greenhouse effect would have disastrous on this planet"s population. Also, melting of parts of the Antarctic ice sheet will cause flooding of coastal cities such as LondonNew York, Beijing, Amsterdam, St.
John"s, Halifax, Vancouvereven Montreal and of entire countries, such as Bangladesh" Johnson, The greenhouse effect is not limited to certain countries or states.
The entire world will suffer if it is allowed to grow.Free Essay: Earth's atmosphere is a unique reservoir of gases, the product of nearly 5 billion years of development. It sustains us and protects us from. NALANDA OPEN UNIVERSITY M.A./iridis-photo-restoration.com (Environmental Studies) PART–I, PAPER–I (Fundamentals of Environmental Science & Ecology) Annual Examination, Our Earth is the most beautiful planet in our solar system.
As far as we know, Earth is the only planet that has life. Before A.D., man had a good relationship with Mother Earth. But since humans developed cities and industries, the modern lifestyle has changed. Man has been using and misusing. Earth Science In reading article “The Origin of Old-Earth Geology and its Ramifications for Life in the 21st Century” by Dr.
Terry Mortenson, it had some very interesting point of views about the Earth’s geology. It only took five minutes for Gavin Schmidt to out-speculate me.
Schmidt is the director of NASA ’s Goddard Institute for Space Studies (a.k.a. GISS) a world-class climate-science facility. One. For example, in the Earth sciences, modeling of atmospheric and ocean phenomena is relevant for not only weather forecasting but also scientific understanding of global iridis-photo-restoration.com the latter case, one model of note is the general circulation model, which is used for simulating human- and non-human-induced climate change..
