(Fretwall et al. 2013; Tinger 1991; Wayman 2013). 2.2 Geology Antarctica is predominantly and permanently covered by thick layer of ice. The Antarctica peninsula is made by uplift and metamorphism of sea sediments which occurred during the late Paleozoic and the early Mesozoic eras. This sediments uplift was complemented by igneous intrusions and volcanisms (Adie 1977). The most common rocks founded in Antarctica are andesite and rhyolite formed during the Jurassic period. It has been found…

1.0. INTRODUCTION Mangroves ecosystem provide an important sources such as food, medicines, material for building and filtering pollution. Mangrove forests are among the economically highest valued ecosystems. However, increase of urbanization and climate change affected the ecological functioning and the goods and services that are provided by mangrove system. Such that, the mangrove large areas are rapidly disappearing. In addition, it is degrade the condition of remaining areas. Additionally…

quite far away and yet they still had a source of clean water that they could do whatever with after it was filtered. Filtration is an example of technology, they had used filtration where the waters were put into containers, where they lose their sediment. The water volume is measured by scales as…

1. What are the eras of the Phanerozoic? Name one important evolutionary event in each of those eras. Paleozoic The big incident of this era is the Cambrian explosion that happened 540 million years ago. Mesozoic Angiosperms were diversified during this era Cenozoic Mammals increase in size 2. Define/explain the following terms: Ediacaran, diagenesis,…

that dead zones have existed long before the news of current, well known dead zones such as the ones that take place in the northern Gulf Of Mexico. To examine and analyze dead zones that existed in the past, Osterman and her research team extracted sediment cores from where the Gulf of Mexico’s most current dead zone took place then dated each core they collected.…

Earth and Environmental Science – Field Report • Statement of purpose: A study was carried out in Orphan School Creek to see how human impacts/activities have affected the area. Orphan School Creek may be a local area but that does not mean it is kept clean and in good shape as many biotic and abiotic features of the environment have been affected by humans. • A clear and detailed definition of the area studied: A number of abiotic features of Orphan School Creek include: - Creek Water -…

the questionable crocoduck. Evolution clearly does not only rely on fossils. The process of a fossil is quite interesting though. The first step is for the creature to fall into a body of water. In the water it must make its way under some kind of sediment in order to preserve the animal. This is a factor to why majority of fossils from is animals that live in water. The fossil must be able to survive the everyday changing of weather on the earth. Once the fossils…

Plate tectonics is the belief the lithosphere is separated into a few dozen plates that move around across the earth 's surface relative to each other, like big pieces of ice on a lake. If we were able to lay the earth flat to see where the plates were positioned, it would have the appearance of an orange peel; with the earth 's crust as the orange color shell and the white as the lithosphere. The break points would be fault lines, the plate’s outer perimeter that aligns and intersects them.…

is the living of importance here, but the physical makeup of the trench is as well. Studying samples and footage taken from this area can provide a lot of information. Rock samples can provide data on the age and formation of the trench. Water and sediment can be studied for their composition and provision of nutrients. But all is not so amazing in the Mariana Trench due to human impact. There has been recent evidence showing pollution with PCBs which were banned chemicals in the 1970s, a Spam…

weather Streams give us a large supply of drinking water in its highest quality by ensuring a continuous flow of clean water. They can reduce the pollution that flows to downstream rivers, lakes, bays, and coastal waters. They are able to retain sediments and excess nutrients, such as nitrogen and phosphorus, and prevent these pollutants from traveling further downstream where they could cause algal blooms or dead zones.…
