Essay for Geography Students on Atmosphere.
The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the.
Specifically, the emission of greenhouse gases such as carbon dioxide may be classified as the primary culprit. As a result of greenhouse gases entering the upper levels of the earth's atmosphere, it diminishes or breaks down the earth's Ozone layer.
The earth then warms up and emits energy back out into space. Without an atmosphere—or more specifically, without greenhouse gases in our atmosphere—our average temperature at the surface would be well below freezing. Thankfully, we have a blanket of gases that keep some of this energy from escaping into space.
Other Greenhouse Gases. While all eyes were turned on carbon dioxide, almost by chance a few researchers discovered that other gases emitted by human activity could have serious global impacts. In the 1970s attention centered on damage to the atmosphere's protective ozone layer, and nations combined to diminish the risk.
Basic Principle Of Co2 Laser Engineering Essay. 2013 words (8 pages) Essay in Engineering.. low-power sealed-tube, high-power flowing-gas and pulsed transversely excited CO2 lasers. CO2 laser is a molecular laser, CO2 laser gas is a mixture of CO2, N2 and He gases. CO2 is a linear, symmetric molecule that vibrates in three different.
B. Carbon dioxide gas from cars and industry is a product of burning that produces heat. C. Carbon dioxide in the upper atmosphere absorbs and re-emits heat radiated from Earth's surface. D. Radiation on Earth's surface is increasing because of a hole in the ozone layers.
This pattern of warming in the lower atmosphere and cooling in the stratosphere is a hallmark of greenhouse gas warming in global climate models. These images show temperature trends in two thick layers of the atmosphere as measured by a series of satellite-based instruments between January 1979 and December 2005.
