Oil/ Petrol Research Project
In the modern world we use oil every second of the day, whether we realise it or not. We use oil to fuel our cars, our public transports, etc. Without oil our daily lives would be the same. Oil is a natural resource that comes from beneath the earth’s crust; it is trapped in pockets under the earth. Finding oil trapped underground is very complicated and costly, it takes millions of dollars to drill a well and only a few are successful. Oil travels upwards from the rock in which the oil is formed, when the oil meets a cap rock (a rock with no spaces in-between the grains) is it trapped. Soon after when oil pockets are found, a well is drilled so that the oil can travel up to the well and be retrieved. After the oil is retrieved it must be separated as the oil is a mixture of water, crude oil and gas and to transport the oil safely you must first separate all the different elements/compounds. After all of this the oil is safely transported to and from countries, across seas, wherever the oil is needed. Most people would say that oil has only a bad effect on the environment it does but not for all the reasons you think. Of course oil causes pollution and destroys our ozone layer however it also a participating factor towards climate change, it helps in making the north and south poles smaller and the oceans bigger. Oil is also a toxin in the oil wells that kills animals, wildlife and the ecosystem that may never be the same again. Nevertheless, oil does have its positive impacts on the environment. When an oil spill occurs obviously the ocean wild life and the ecosystems are damaged for months on end however when oil is spilt in the ocean it can also locate significant deposits of oil. Also because there has been very large oil spills, not regularly but oil spills that take months to clean up, organisms have adapted and have learnt to feed on these oil spills. The oddest thing about the organisms is also the fact that they didn’t just...
