add various gases to the earth’s atmosphere every day; these gases (known as “greenhouse gases”) consist primarily of carbon dioxide, ozone, chlorofluorocarbons, nitrous oxide, and methane, and tend to warm the earth. Trees help counter greenhouse gas production during photosynthesis, by taking in carbon dioxide as waste material and producing oxygen, which of course we all need to survive. Scientists predict that the daily addition of greenhouse gases to the atmosphere, combined with daily removal

windows and damaging buildings. Definition : Small pieces of space debris — usually parts of comets or asteroids — that are on a collision course with the Earth are called meteoroids. They become meteors when they enter the Earth's atmosphere. Most meteors burn up in the atmosphere, but if they survive the frictional heating and strike the surface of the Earth they are called meteorites. The site of Friday's spectacular show is about 5,000 kilometres west of Tunguska, which in 1908 was the site of

began. There have been several periods throughout history where surface temperatures have been higher or lower. According to Philip’s Encyclopedia (2008), “The earth is currently in the middle of a warm period that began 10,000 years ago.” The earth’s temperature has been rising since the 19th century. Historical records indicate the sea levels have risen and glaciers are receding. The Encyclopedia of Ecology states, “There has been an increase in the atmospheric concentration of carbon dioxide

the increase in the earth’s temperatures as a result of human activities such as the burning of conventional fossil fuels, factory emissions, agricultural processes and greenhouse gas emissions. The human activities cause too much carbon dioxide to be emitted into the earth’s atmosphere resulting in global warming. The global warming processes involves the sun light waves entering and heating up the earth atmosphere and then are reflected back as infrared waves into the atmosphere. These infrared waves

WHAT IS THE GREENHOUSE EFFECT? Seen from space, our atmosphere is but a tiny layer of gas around a huge bulky planet. But it is the gaseous outer ring and it is misleadingly called greenhouse effect that makes life on EARTH possible-and that could destroy life as we know it. The sun is the Earth’s primary energy source, a burning star so hot that we can feel its heat from over 150 million kilometers away. Its rays enter our atmosphere and shower upon on our planet. About one third of this

of fossil fuels would cause global temperatures to rise by trapping excess heat in the earth’s atmosphere. a. Arrhenius (1896) understood that the earth’s climate is heated by a process known as the Greenhouse effect b. small concentrations of greenhouse gases like water vapour and carbon dioxide convert some of this energy to heat and either absorb it or reflect it back to the earth’s surface. c. Sunlight passes through, but a certain amount of radiated heat remains

warming is the gradual increase of the temperature of earth's atmosphere and oceans. Over the past century the average temperatures have gone up by just over one degree. This may not seem like much, but many scientists agree that the earth's temperatures are starting to increase at a faster rate. What causes it? Global warming occurs when greenhouse gases, such as carbon dioxide, nitrous oxide, and methane trap heat inside the earth's atmosphere. Think about what happens when you open your car door

is released from environments. This gas if for a purpose in global warming’s natural causes. Greenhouse gas is a gas that traps heat in the earth’s atmosphere. Shorter wavelength radiation from the sun passes through the earth’s atmosphere and it is then absorbed by the surface of the earth causing it to warm. Large amounts of methane entering the atmosphere could lead to abrupt changes in the climate that could be irreversible. Methane has about 20 times the heat trap effect of an amount of carbon

earth came to being and all life was formed. The video in its varied forms tells us how the earth’s resources are depleting day in and day out and the reasons for the same are we humans. Destroyers of all!! As known by all, in the beginning the earth was a mass of nothingness. But gradually, over a period of years life began to form from the bacteria that fed off the earth’s heat. Life altered the atmosphere. It got its energy from the sun. Life is a link between innumerable life forms that have succeeded

Aleksey Golubok Friday 1 PM 10/8/15 Global Warming and Climate Change I. According to data from NASA, the overall temperature in the earth’s atmosphere has been increasing since 1880. Most of this warming, however, has occurred since 1970, with the 20 warmest years having occurred since 1981 and with all 10 of the warmest years occurring in the past 12 years. This phenomena, known as global warming or climate change, is caused by the greenhouse effect. Gases such as carbon dioxide, chlorofluorocarbons
