Released Into The Atmosphere Greenhouse Gases
958 wordsGlobal warming is an increase in the earth's temperature due to fossil fuels, industry, and agricultural processes caused by human, natural, and other gas emissions. (Melissa Phillips). This results in an increased emission of greenhouse gases. (Caroline Quatman). Short-wave solar radiation sinks into the Earth's atmosphere and warms its surface; while longwave infrared radiation emitted by earth's surface is absorbed, and then re-emitted by trace gases. (Brent C. Willhoite) Climate changes occu...

Plan for pH I am going to use the three categories of acid, neutral and alkaline to test how pH affects the rate of the enzyme rennin. Whilst studying the affects of varying the pH, I am going to ensure that all other variables are constant. Therefore, I will continue to use 2 ml of milk and 4 drops of rennin. The temperature I shall conduct these expe...

Many of the minerals that develop there could be minded safely and used by humans (Chu). In addition to these, there are many more reasons why vents are, and are potently important to humans. Introduction to Tube Worms Up until recently it was thought that nothing could ever live at hydrothermal vent sites. The vents hostile conditio...

Back Into Space Greenhouse Gases
2,020 wordsIn my seminar work I will try to explain you what is happening to global climate, which are the consequences and what can we do to stop changing our climate. Humans are heating the planet. Official confirmation for that came in 1995, when the Inter-Governmental Panel on Climate Change (IPCC) the official scientific body established in 1988 by the UN to investigate climate change - published its Second Assessment Report, written and reviewed by some 2 000 scientists. A consensus now undeniably ex...

Atmospheric Co 2 Carbon Dioxide
1,549 wordsClimate change will have significant impacts on the global temperature such as an increase in temperature, change in weather patterns and sea-level rise. Sea-level is expected to rise 95 cm by the year 2100, with large local differences due to tides, wind and atmospheric pressure patterns, changes in ocean circulation, vertical movements of continents etc; the most likely value is in the range from 38 to 55 cm. The relative change of sea and land is the main factor: some areas may experience sea...

Carbon Dioxide Emissions Back Into Space
2,423 wordsGlobal Warming and Our Oceans Global warming and climate change has become one of the most heated environmental issues recently that has triggered a lot of controversial responses. Because sunlight is constantly falling on the earth, the law of physics says that the planet has to radiate the same amount of energy back into space. Infrared radiation is sent out by the earth through the atmosphere, where molecules (carbon dioxide) hold outgoing radiation for a while, warming the surface. The molec...

Stop Global Warming Carbon Dioxide
1,721 wordsEFTHIMIOS MARIAKAKIS The greenhouse effect and global warming are issues that are talked about by geologists all the time. The greenhouse effect is a natural process that keeps the earth at temperatures that are livable. Energy from the sun warms the earth when its heat rays are absorbed by greenhouse gasses and become trapped in the atmosphere. Some of the most common greenhouse gasses are water vapor, carbon dioxide, and methane. If there were no greenhouse gasses, very few rays would be absor...

Nitrous Oxide Greenhouse Gasses
3,082 wordsThe Global Warming Global Warming The world is getting hotter. 1998 was the hottest in one thousand years, and the nine hottest years on record have all been in the past two decades. Humankind's actions on a global scale have changed not just the landscape of the Earth, but the worlds climate too. Increasingly sophisticated measurements of the worlds climate and weather systems have provided a wealth of evidence that the Earth has been getting steadily warmer. Since the beginning of the industri...

Burning Fossil Fuels Natural Greenhouse Effect
3,312 wordsThe Greenhouse Effect The greenhouse effect, as defined in the dictionary, is the effect produced as greenhouse gases allow incoming solar radiation to pass through the Earths atmosphere, but prevent most of the outgoing infrared radiation from the surface and lower atmosphere from escaping into outer space. Even though this process occurs naturally and has kept the Earths temperature about 60 degrees Fahrenheit warmer than it would otherwise be, current life on Earth could not be sustained with...

Polar Ice Caps Rise In Sea Level
2,227 wordsThe Greenhouse Effect Issue Statement While some people believe the earths climatic changes are due to the fact that the universe is getting older, others believe it is due to the greenhouse effect. The greenhouse effect is a naturally occuring phenomenon that is responsible for trapping heat near the earths surface and keeping the planet warm. It is called the greenhouse effect because the way it works is similar to the way in which a green house functions. In a greenhouse sunlight passes throu...

Times Per Minute Body Temperature Falls Hibernation
1,829 wordsHibernation: Definition Hibernation is an inactive, sleep like state that animals must go and at least one bird enter during the winter. Animals that hibernate shelter themselves from harsh winter and reduce their need for food. Their body temperatures are considerably lower, as well as their heartbeat and breathing. The true hibernator spends most of the winter in a state close to death; in fact the animal may appear to be dead. The body temperature is close to zero degrees; the respiration is ...
