In North Carolina many of us have been effected in some way by tornados, hurricanes, and maybe even an earthquake, but I would bet that none of us have been effected by the worse natural disaster the tsunami. Historically, tsunamis have been caused by a plethora of different events. Some of these are underwater earthquakes, volcanoes, and landslides. Many people might recognize earthquakes as a violent shake in the earth’s crust and this is true, but tsunamis can be more powerful causing a greater damage. Tsunamis happen when the plates on the crust of the earth move, therefore moving the entire plate so that the water rises and is pushed forward, therefore causing a tsunami (Drohan, 2009, p.21).
In the US alone, the Office of Response and Restoration of the National Oceanic and Atmospheric Administration (NOAA) responds to over a hundred oil spills each year (NOAA). While spills happen on both land and water, ocean spills are much more difficult to contain and recover from. They happen easily, almost too easily, either caused by carelessness, accidents, or natural disasters, and their negative environmental impacts could take decades to recover from. It seems like as long as humans are still depending on oil, spills will continue to wreck havoc on marine life. Oil harms marine animals both physically and chemically.
BP, with the assistance of government agencies and others, worked together to manage the spill and mitigate its impact on the environment and human health by eradicating and dispersing the oil offshore, and by executing strategies to preserve the seashore and clean up oil that came ashore. Besides, there is still 28 percent of oil in the sea (Bryant, 2011). Every disaster is followed by fatalities, however, this disaster had double or even triple number of losses than any other disasters. The Gulf oil spill not only affected sea and marine life, but also humans who were used to live on the coastline. From the sociological perspective, it was a huge social, cultural, economic and psychological threat for the communities living across the coastlines, cleanup workers, and especially children.
Dispersants cause the oil to break up into smaller droplets, which become miscible in water. However, these dispersants may result in more ecological harm than good. The chemicals contain nonbiodegradable toxins that can kill fish and migrate great distances. Dispersants also are blamed for the massive oil plumes several hundreds of feet underwater, harmful to all aquatic life, especially fish larvae and filter feeders. Moreover, because of the large volume of oil that has been spilled, the amount of dispersant required and the amount of oil dispersed simply suppresses the problem, rather than solving
Finally, the transform boundary, where plates slide *alongside* each other. These movement cause many natural disasters such as earthquakes, volcanoes and tsunamis. alongside: move side by side Figure 2 : This is a map of our 12 major tectonic plates Causes of most natural disasters Have you ever wondered about how earthquakes, tsunamis and volcanoes were all created? They were created because of this movement of the plates or continental drift. Earthquakes Earthquakes are created in transform boundaries which is when two plates move alongside each other.
The active ingredients in the alka seltzer tablet are “As the tablets dissolve, the sodium bicarbonate splits apart to form sodium and bicarbonate ions. The bicarbonate ions react with hydrogen ions from the citric acid to form carbon dioxide gas (and water). This is how the bubbles are made.”(Scientific American) These bubbles are representative of a chemical change and the resulting carbon dioxide should increase the water 's density. This may actually increase the volume of the water taking longer to boil, this difference may be minuscule, even negligible, but there 's a possibility for distinct change in results. This scientific American puts it best “For the reaction to occur,
Oceans are polluted by oil daily from oil spills, routine sea shipping, runoffs, and dumping oil straight into the ocean. An oil spill is the discharge of petroleum into habitats by vehicles, vessel or pipelines. It occurs extensively and it mostly takes place in water bodies. It happens due to human carelessness. Spilled oil can harm marine animals because its chemical components are poisonous.
In Western Canada, Oregon California and Hawaiian Island a Pacific-wide tsunami was produced which was destructive in. The death rate from the earthquake was about 128 people. Most of the deaths were in Alaska 115, Oregon had 15 and Washington were caused by quake-generated tsunamis. The human toll could have been much larger. However, the low population in the immediate area of the quake (and Alaska’s relatively low population density in general) as well as the fact that the earthquake occurred on a holiday limited the loss of life from the event.
Oil is often used to meacheans today and it was a valuable resource at the time The Jungle took place. Drilling for oil can be risky when it comes to the environment, one method for getting oil is called fracking. Fracking is the action of pushing high pressure water into the Earth deep underground, this force opens up cracks and fissures in the ground to extract oil or gas. However fracking does not come without counsusquses, if done enough fracking can lead to changes to the tectonic plates underground. If fracking continues in these areas, earthquakes can occur in Oklahoma there have been recorded of small earthquakes While these earthquakes are small they should not be happening at all, Oklahoma is near the center of the North American Tectonic Plate.
Oceans are vast water bodies, and large quantities of wastes have been dumped into them under the assumption that its not a serious problem. But recently many reports show that ocean waste is accumulating at remote sea shores causing problems to the local people there. This has brought into light that dumping waste in oceans is not sustainable. Earlier, the wetlands used to help filter out a major share of the pollutants from the runoff before it joins the surface water. As cities expanded, most of the wetlands got converted for construction
