with Citizen Kane in 1941‚ lens flare was first used intentionally in film. Lens flare is a result of particulate matter (matter that changes state within the atmosphere) interacting with light and‚ additionally‚ getting itself trapped inside a lens. Atmospheric optics deals with how the unique optical properties of the Earth’s atmosphere cause a wide range of spectacular optical phenomena. The blue color of the sky is a direct result of Rayleigh scattering which redirects higher frequency

So from what has been said‚ scientists are saying that we are changing the atmosphere and that it is causing damage. So why not do our

My focus will be on the relationship between Unoka and Okonkwo. I chose that topic because it is interesting to find out how father and son can differ in so many ways. Eventhough they are directly blood related‚ Unoka and Okonkwo have a very different characteristic. Unoka the father was a very lazy and wasteful man‚ while Okonkwo is everything Unoka was not. Many people have been asking the same question on this strange matter since they are more familiar with the saying ‘like father‚ like son’

carbon‚ and halocarbon. These gases absorb the heat radiated from Earth’s surface and lower atmosphere while radiating most of the energy back toward the surface. The humane activities such as transportation‚ mining‚ agriculture‚ fossil fuel burning‚ and many others have increased the concentration of these gases. The result is a thick blanket in the atmosphere of these “heat trapping gases in Earth’s atmosphere‚ causing surface temperature to rise.” http://www.globalchange.gov/publications/repor

What impact might CO2 emissions have on overall global warming? In the 19th century‚ scientists realized that gases in the atmosphere cause a "greenhouse effect" which affects the planet’s temperature. These scientists were interested chiefly in the possibility that a lower level of carbon dioxide gas might explain the ice ages of the distant past. At the turn of the century‚ Svante Arrhenius calculated that emissions from human industry might someday bring a global warming. Other scientists dismissed

Since the beginning of the early 20th century‚ the earths mean surface temperature had increased by around 0.8 degrees. Warming of the climate system had become more obvious and scientists are 90% sure that the main cause of the increase in temperature in due to the increasing concentrations of greenhouse gases due to human

releasing more and more greenhouse gases into the atmosphere for a variety of reasons. We are doing this by burning fossil fuels. When fossil fuels are burned‚ they release harmful greenhouse gases into the atmosphere. These greenhouse gases then remain in the atmosphere‚ and trap most of the heat from the Sun‚ causing the global temperatures to increase. There are three main reasons for why humans are beginning to put more greenhouse gases into the atmosphere. The main thing we use fossil fuels is to

the planet. It reaches a surface temperature of 900° F. This is hotter than Mercury‚ which is closer to the sun. This temperature is hot enough to melt lead. This higher temperature is attributed to a runaway greenhouse effect caused by the heavy atmosphere of carbon dioxide. This would also probably account for the lack of water on the planet. The oceans‚ if there were ever any‚ were probably boiled away millions of years ago. The extremely hot temperature also attributes to the fact that no life

I think that acid rain is not really safety because it might give us trouble breathing. Some carbon dioxide is normal in the atmosphere‚ ant it helps creating clean atmosphere‚ preventing Earth from being frozen. Acid rain also makes the oceans more acidic. Acid rain is bad and good at the same time‚ so depend on
