How can alternative sources of energy be harnessed effectively? We are running out of our most important natural source of energy, fossil fuels. Fossil fuels are non-renewable natural fuels that were formed by the decomposition of animal and plants that lived up to 100-300 million years ago and humans cannot manufacture Fossil Fuels. The price of fossil fuels is also rising across the globe and when the fossil fuels are burned, it damages the already deteriorated environment. The burning of the fossil fuels is also the main contributor to global warming.
The water that I placed activated carbon in actually increased by 2pH rather than decreasing. 3. Based on your data, what effect do you predict coal mining has on the environment? Answer = Coal mining is the removal of coal from the earth which slows the Earth's capability to decrease the acidity of groundwater. If an ideal pH level is 7 than the carbon was able to take our acidic water and make it more neutral.
| | In biological magnification toxins concentrate at higher trophic levels because at these levels biomass tends to be lower. | | Sometimes harmful substances persist for long periods of time in an ecosystem and continue to cause harm. | | Since the Industrial Revolution, the concentration of CO2 in the atmosphere has increased greatly as a result of burning fossil fuels and wood removed by deforestation. | Carbon Dioxide Problems | One pressing problem caused by human activities is the rising level of atmospheric carbon dioxide. | | The FACTS-I experiment is testing how elevated CO2 influences tree growth, carbon concentration in soils, and other factors over a ten-year period.
Australia has recently signed to Kyoto Protocol which aims to reduce greenhouse gas emission by 4 million tonnes becoming 2010. Companies have improved scrubbers, which clean sulfur from the smoke before it leaves the smokestack. Awareness is growing when considering pollution from coal. Here in Australia while we are monitoring carefully the atmospheric pollution caused by coal burning it can be stated categorically that Carbon dioxide emissions from vehicles have far more reaching effects than the pollution created from coal. Coal will continue to be used extensively in Australia because of it's abundance.
http://www.enchantedlearning.com The Carbon Cycle: In the atmosphere, carbon is attached to some oxygen in a gas called carbon dioxide. Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.
For instance Carbon Dioxide from the atmosphere is synthesized by plants, which is ingested and metabolized by animals, which is converted to Carbon Dioxide during respiration and decay. Humans remove over 40% of the photosynthetic that effort plants in order to support human enterprises. When humans burn fossils fuels that increases the atmosphere Carbon Dioxide by 35%, then during the combustion stage the present of air (oxygen), Carbon Dioxide and water molecules are release into the atmosphere. Human has an impact on the Phosphorus Cycle as well as the Carbon Cycle. The Phosphorus Cycle is representative of the cycle of all biologically important mineral nutrients-those elements that have their origin in the rock and soil minerals of the Lithosphere, such as iron, calcium, and potassium.
What are the savings of BOTH carbon emissions and money you can achieve via each solution? a. How much would this amount to if every household in America (roughly 100 million) did this? Each person would 11,141 lbs of CO2 per year and save $416 a year b. If everybody did this, what might the impact on the health of our environment be?
Although we may be able to sustain a planet with some kind of civilization, the earth that we knew is gone. Oil and fossil fuels are attributed to manual labor and why we are prosperous and why our economies have grown. It is also why we have global warming and acid oceans. Rising temperatures and depleting oil reserves go hand in hand. Modernity may cease with global warming as half the biggest companies are oil companies, and oil is the essence of life.
Coal hypothesis = If activated carbon is added with 100mL of water, it will increase the pH over 48 hours. 2. Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this. a. Pyrite hypothesis accept/reject = I would accept the hypothesis, seeing as how the pH reduced from 6 to 2. b.
In the coal gasification process the air and stream are added to the raw coals then heat it to hundred degrees Fahrenheit. The carbon in the coal then react with the oxygen and the water then produces other gases such as carbon dioxide, carbon monoxide, hydrogen and methane. The carbon dioxide from the process is waste and can go to the atmosphere. The other gases can be burned or sent to the next process. Then the second process is after we get the processed and filtered coal, gas or water or carbon dioxide can be added to balance the amount of carbon monoxide and hydrogen.
