process. First‚ sunlight radiates from the sun‚ through space‚ to Earth’s atmosphere. Second‚ 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. Third‚ greenhouse gases trap infrared rays that are remitted into the atmosphere. Finally‚ the gas then absorbs the light and is remitted back to the Earth’s surface and warms it even more. Left on it’s own this natural process

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 warm the planetary surface‚ which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases‚ which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is named after the effect of solar radiation passing through glass and warming a greenhouse‚ but

What is the impact of human activity on the natural environment? Answer: Humans are a part of the natural environment. Unfortunately‚ we have not yet learnt to moderate our activities in such a way as to help the environment. Human activities often lead to degradation of the environment. Impacts of humans include: • pollution - land‚ freshwater creeks and rivers‚ seas and oceans‚ and air • deforestation and destruction of habitats • endangerment and extinction of flora and fauna species

and warms the earth. Most of this light reaches the earth’s surface as short-wave radiation. When short wave radiation from the sun hits the earth’s surface it changes to long-wave infrared radiation‚ which bounces back into to space ("National Geographic"). However‚ there is a certain percentage of long-wave infrared radiation trapped by greenhouse gases in the atmosphere. On absorption and subsequent reflection of long-wave radiation to the surface of the earth‚ more heat is conserved on the surface

Global Warming: Origins‚ Effects‚ and Potential Solutions Since the dawn of the 19th century‚ civilization has been very dependent on the consumption of fossil fuels. Greenhouse gases‚ especially carbon dioxide‚ coming from these emissions plague our atmosphere. Greenhouse gases trap heat and prevent warmer air from escaping our atmosphere‚ which causes a containment of excess heat‚ thus causing a climate change; in this case‚ a rise in temperature. There has been large amounts of debate on whom

(FIGURE-4) In order to tell how much borneol is formed during reactions‚ both qualitatively and quantitatively‚ infrared spectroscopy and gas chromatography are executed on the products formed from Sodium Borohydride Reduction and Meerwein-Ponndorf-Verley Reduction (MPV). Infrared (IR) spectroscopy shows the relative absorption of specific chemical bonds in a molecule to the induced infrared radioactive energy. Thus from looking at the peaks on IR spectrum‚ possible functional groups in a compound
