Chlorofluorocarbons Cfcs Nitrogen Oxides
1,336 wordsDramatic loss of ozone in the lower stratosphere over Antarctica was first noticed in the 1970 's by a research group from the British Antarctic Survey (BAS) who were monitoring the atmosphere above Antarctica from a research station. The Halley Research Station BAS research stations in the Antarctic Rumor has it that when the first measurements were taken in 1985, the drop in ozone levels in the stratosphere were so dramatic that at first the scientists thought their instruments were defective....

Grendel And His Mother Seamus Heaney
932 wordsThe poem Beowulf, translated by Seamus Heaney, is largely based around the monstrousness of Grendel and his mother. It was a difficult task for Heaney to translate the poem into Modern English while maintaining the beauty of the language and capturing the horror of the monsters.

Digestive Juices Digestive Tract
1,493 wordsDigestive System, series of organs put together that purpose is to break down, or digest, the food we eat. Food is made up of large things called, complex molecules, which the digestive system breaks down into smaller things called simple molecules that get absorbed into the bloodstream. The bloodstream is our blood. The simple molecules travel through the bloodstream to all of the parts of the body, which we use for growth, repair, and energy. All living things that eat to get energy have a dig...

White Blood Cells Parts Of The Body
1,025 wordsCirculatory System is the combined function of the heart, blood, and blood vessels to transport oxygen and nutrients to organs and tissues throughout the body and carry away waste products. The circulatory system increases the flow of blood to meet increased energy demands during exercise and regulates body temperature. Also, when foreign substances or organisms invade the body, the circulatory system quickly sends disease-fighting elements of the immune system, such as white blood cells and ant...

Surface Of The Earth Released Into The Atmosphere
328 wordsatmosphere is to insulate and warm the surface of the earth. The greenhouse effect is not a new phenomenon. Humans can help reduce the increasing greenhouse effect. The atmosphere insulates and warms the surface of the earth. Incoming solar radiation passes through the atmosphere. The surface of the earth absorbs some of the radiation. The unabsorbed radiation is emitted back out in the form of infrared radiation. Gases, such as, carbon dioxide, methane, nitrous oxide, and water vapor absorb the...

H 2 O Carbon Dioxide
854 wordsColours Chloroplasts contain several different pigments the majority of which are chlorophyll a and chlorophyll b. Both of these types of chlorophyll absorb similar wavelengths of light, but chlorophyll a absorbs a slightly higher wavelength than chlorophyll b. Neither chlorophyll absorbs much light in the green region of the spectrum thus making it appear green. This can be plotted onto a graph (fig 1. 1). This graph is called the Absorption Spectrum. The Absorption Spectrum is very similar in ...

Polar Ice Caps Rise In Sea Level
817 wordsGlobal Warming Global Warming, aside from pollution is one of scientists biggest concerns. Global Warming is caused by the Greenhouse effect. There are 4 steps in the Greenhouse effect process. The first is, sunlight radiates from the sun, through space, to the Earth s atmosphere. The second is, sunlight enters the atmosphere and hits the Earth. Some of that sunlight turns into heat energy in the form of infrared light. Surrounding air and land, which in turn makes the heat warm, absorbs the hea...

Source Of Energy Earths Surface
683 wordsAll life on Earth depends on energy from the sun. Solar energy is the source of energy for photosynthesis. It provides the warmth necessary for plants and animals to survive. The heat from the sun causes water on the Earths surface to evaporate and form clouds that eventually provide fresh rainwater. Solar energy is the result of thermonuclear fusion reactions deep within the sun. These reactions produce so much energy that they keep the surface temperature of the sun at about 10, 300 B 0 F. Eve...

Ultraviolet Rays Uv Rays
633 wordsThe ozone layer shields the earth from most of the harmful radiation and light comming from the sun. The ozone reflects and absorbs the ultraviolet rays that try to come in. Without this kind of protection, all living things will be effected by these UV rays. Skin cancer develops in most living mammals as a cause of an overabundance of the suns ultraviolet rays. The ozone layer is located in the earths stratosphere. The ozone layer is located from about fifteen-to-thirty kilometers above the ear...
