  • Global Warming And Its Causes
    2,291 words
    Global Warming Global warming is the warming near the earth's surface that results when the earth's atmosphere traps the sun's heat. The earth is getting warmer. The changes are small, so far, but they are expected to grow and speed up. Within the next fifty to one hundred years, the earth may be hotter than it has been in the past million years. As oceans warm and glaciers melt, land and cities along coasts may be flooded. Heat and drought may cause forests to die and food crops to fail. Globa...
  • Greenhouse Carbon Dioxide
    817 words
    The Greenhouse Effect The greenhouse effect is an increase in the atmospheric temperature caused by increasing amounts of greenhouse gases. These gases act as a heat blanket insulating the Earth's surface absorbing and trapping heat radiation which normally escapes from the earth. They include carbon dioxide, water vapor, methane, nitrous oxide, CFC's, and other halocarbons. The earth's atmosphere goes through two processes constantly. Global cooling is the first process. This process uses the ...

    Bush Won't Regulate Carbon Dioxide Updated 7: 30 PM ET March 13, 2001 By SCOTT LIND LAW, 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 warmin...

    Carbon Monoxide Poisoning Imagine that it is the first really cold night of the winter season. You begin to feel a chill in the house so you decide it's time to turn on the furnace. So you get up out of your chair and adjust the thermometer. After a while you notice that it has not really warmed up much in the house. So you decide to check it again just as soon as you get something for this awful headache that just came on. But, as you get up out of your chair you almost fall over because you a...

    Fossil Fuel Consumption, CO 2 and Its Impact on Global Climate Background: At the beginning of human history, we had to satisfy our energy needs (for food, heat and movement) by using our own muscle power and gathering or hunting naturally available plants, animals and wood. 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...
  • Greenhouse Effect Carbon Dioxide

    GREENHOUSE EFFECT The glass windows of a greenhouse let in sunlight. The sunlight warms up objects inside the greenhouse. These objects then give off heat. The glass of the greenhouse, however, does not let out the heat. If the greenhouse lacks ventilation, all the heat stays locked inside and the temperature rises. This greenhouse effect also causes the inside of an automobile to become hot if its windows remain closed on a sunny day. The Earth and its atmosphere are like a giant greenhouse. L...
  • Green House Effect Carbon Dioxide

    The Greenhouse Effect The Earth is kept warm by it's atmosphere, which acts rather like a woolly coat - without it, the average surface temperature would be about -18 degrees Centigrade. Heat from the sun passes through the atmosphere, warming it up, and most of it warms the surface of the planet. As the Earth warms up, it emits heat in the form of infra-red radiation - much like a hot pan emits heat even after it's taken away from the cooker. Some of this heat is trapped by the atmosphere, but ...
  • Global Warming Carbon Dioxide

    Global warming occurs when the levels of greenhouse gasses rise and less infrared light, or heat, escapes the earth's atmosphere. Thus, the temperature experienced on Earth begins to rise. Climate change is a part of the Earth's history. There have been dramatic fluctuations in overall average temperature for the past 150, 000 years that suggest a direct association with carbon dioxide levels. In the past the temperature highs and lows have been in tandem with carbon dioxide level highs and lows...

    Global Warming is a big problem in today s society. Global Warming also known as the Greenhouse effect is a problem everyone will soon have to face. The people of the younger generations should be educated about what Global Warming is and that it is caused due to the way people are treating the environment. We are now entering the Greenhouse century as we know it. Planet Earth is estimated to be 4. 5 billion years old, and life on earth has existed for more than 3. 5 billion years. Humans have ...

    A Diamond is one of the two natural minerals that are produced from carbon. The other mineral is Graphite. Even though both of these minerals are produced from the same element, carbon, they have totally different characteristics. One of the most obvious difference is that Diamond is hard and Graphite is soft. The Diamond is considered to be the most hardest substance found in nature. It scores a perfect ten in hardness. Because of its hardness a tiny Diamond is used as a cutting and drilling t...

    Colours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in...

    Ideally, analysis of the materials found on a site begins in the field laboratories while excavation is still in progress. Often, however, reconnaissance and excavation are completed in a relatively brief period of time, and the records and preserved remains are taken back to a museum, university, or laboratory for more analysis. This analysis has many aspects, which include describing and classifying objects by form and use, determining the materials from which they were made, dating the object...

    The greenhouse effect, what exactly is this? The sun supplies the energy to warm the earth. The atmosphere absorbs outgoing reflected thermal radiation to keep then earth warmer than it would be otherwise. That is the greenhouse effect. Just like a greenhouse, it stays warm because the closed windows prevent the air from inside to cool by circulating. The main concern about the greenhouse effect is the constant warming of the earth. Scientists fear that this warming may be a risk to humans, pla...
