Essay Question: Describe and explain how rock cycle operates. How do rocks metamorphose at destructive plate boundary? Rock cycle is a cycle that describes how rocks are transformed. Igneous rock can change into sedimentary rock or metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Besides‚ metamorphism at the destructive plate boundaries creates different characteristics of rocks. Operation

Oil Spills Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth. Pollution is the ocean directly affects ocean organisms and indirectly affects human heath and resources. Oil spills is one of the harmful materials that are a major source of pollution in the ocean. “Oil spills stem from accidents involving tankers‚ barges‚ pipelines‚ refineries‚ and storage facilities‚ often while the oil is being transported to its users.” (NOAA 2012) Based on information

An Ekman grab was used to collect the sediment that possessed macro fauna and the meiofauna samples was extracted from sediment corers respectively. Zooplankton was sieved and collected using a 200 micron mesh at the high energy swash zone. The results showed a great variation of species present in the estuary system. Results showed

In the article “Houston Flood Waters Are Tainted With Bacteria And Toxins‚ Tests Show” by Sheila Kaplan and Jack Healy‚ flood waters in Houston neighborhoods have been contaminated. Plus‚ the spread of the toxic waters is not clear on how far they have gone‚ but it is hinted that the breaches of several waste plants have made the waters more dangerous. Testing has occurred and has found traces of Escherichia coli which is a fecal contamination. In the Clayton Homes public housing development‚ high

As well as salt‚ they also need to be in fairly clear waters to allow light to provide energy‚ the deeper the coral reef goes‚ the less creatures are found living in them. High levels of suspended sediments can smother the colonies to death. Even though there are a large amount of coral reefs spread out over the globe when you put them together there are not very many of them.

Topography does not play a major role in the extent of these glaciers. Ice sheets and ice caps fall into the same category. The difference between them is one of scale. Ice sheets are larger.

was the largest controlled sediment release in a dam removal project anywhere in the world. Because of the amount of sediment behind large dams like the Elwha‚ the demolition must be done gradually over time to ensure that there is not an overflow of sediment rushed down the river which could cause significant damage to the landscape and the organisms which inhabit it. At the time of the dam removal the Elwha was holding behind it 15‚000‚000 cubic yards of silt. Sediment buildup isn’t the only thing
