English 11 March 9‚ 2015 The Greenhouse Effect Without the greenhouse effect the temperature of this planet would decrease by at least 30 degrees celsius‚ and it would be too cold for us to survive. The light we receive from the sun keeps our atmosphere warm. The earth only absorbs 30% of the sunlight because the other 70% is reflected back into space‚ and is absorbed by greenhouse gases. These gases act like a mirror‚ and reflect heat back to earth. The major greenhouse gases are carbon dioxide

Environmental Issue Essay – The Greenhouse Effect The Greenhouse effect is a natural process that is imperative for our survival‚ warming the Earth’s surface. The sun emits energy that reaches the Earth’s atmosphere‚ some of it is reflected back to space whilst the rest is absorbed and re-radiated by greenhouse gases such as carbon dioxide‚ methane‚ water vapour‚ nitrous oxide‚ ozone and chlorofluorocarbons (CFCs’). The energy that is absorbed warms the atmosphere and the Earth’s surface maintaining

Animal and plant species have begun dying off or changing sooner than predicted because of global warming‚ a review of hundreds of research studies contends. These fast-moving

Air pollution and greenhouse gases are the two

The Greenhouse Effect This essay is going to describe what the greenhouse effect is and what it does.It is also going to say what causes the greenhouse effect and the consequences of it. 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

GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere‚ it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to

The greenhouse effect‚ first discovered by Joseph Fourier in 1824‚ and confirmed by Svante Arrhenius in 1896‚ is the process by which an atmosphere warms a planet. The term greenhouse effect may be used to refer to two different things nowadays: the natural greenhouse effect‚ which refers to the greenhouse effect which occurs naturally on Earth‚ and the enhanced greenhouse effect‚ which results from human activities. While the greenhouse effect is a natural process‚ the enhancement of this process

Greenhouse Effect 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 blanket engulfing us in heat. This situation is know as the greenhouse effect

The Greenhouse Effect 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. These 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 be below the freezing point of H20. The gases have this effect because as incoming solar radiation strikes

and inert gases. Human activities can release substances into the air‚ some of which can cause problems for humans‚ plants‚ and animals. There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles
