evidence that supports the long term climate change but the plate tectonics hypothesis does not support anything else. And while the other hypothesis support the reasoning behind the short term changes and the reasoning for the iridium found in the sediment layer of clay found at the boundaries both have there holes. While the Alverez Hypothesis has more evidence to support it than that of the volcanic eruptions neither hypothesis go into detail about why the extinctions of species was…

Topic: The importance of preserving Mangroves in Jamaica. Research Question: What is the importance of preserving Mangroves in Jamaica? Thesis statement- The preservation of mangroves provide a good natural nursery ground for marine life, act as sediment filtration system and as a wave buffering zone against hurricanes. Introduction Mangroves are mainly tropical plants with a tangled root system that grows at the interface between land and sea zones of sheltered tropical shores and island.…

phase, a solid, is dispersed in a second phase, generally a liquid.'' (1) There are many characteristics of suspensions that are relevant when formulating such a dosage form. They are as follows; (1) Whilst in storage the suspended particles can sediment to the bottom of the bottle. While this is a normal occurance for suspensions upon standing, thought needs to be given to the redispersal of the suspended particles. Upon shaking of the bottle,…

Generally, scientists have narrowed it down to three different ways these islands have formed: offshore drive, spit accretion, and submergence. Offshore drive is driven by high wave energy stirring up sediment near the coast. Then the waves lose their energy and allow for the sediment to deposit and over time build up enough to break the surface of the ocean. The second theory, spit accretion, essentially occurs when violent storms break the connection to the mainland and thus form an island…

minerals that were in such high demand in the chemistry industry was the fluorite mineral [1]. In 1961, in Stava, there were mining organizations in the mountains of the city looking and discovering many different sources of fluorite in the rock and sediment. Throughout the years of digging the material and minerals up, it caused sludge water and other toxic excrements to seep from the mountains of Stava. Throughout the next…

Some of the many chemicals that are polluting the Chesapeake Bay are polychlorinated biphenyls (PBCs), polycyclic aromatic hydrocarbons (PAHs), pesticides, and personal care/pharmaceutical products. PBCs are a flame retardant that cannot legally be made in the USA, but are legally imported and pollute the bay about evenly throughout. When gas, oil, or coal is burned, PAHs can be formed. PAHs are found mostly around Baltimore and near the Anacostia and Elizabeth rivers. Since agriculture is…

The introduction of the Piscinae before the intake duct (Figure 7) reduces the velocity of flow and increases the depth of the water, which, from Equation 1 we can see significantly reduces the sediment carrying capacity of the water, ensuring a cleaner water supply for Rome. Smaller Piscinae were scattered through the length of the aqueduct (Figure 8) to further purify the water. {Roman Aqueducts nad water supply hodge p101-102}. They were also…

000 people. The proximity, of what is one of Canada’s largest contaminated sites, to a highly populated community poses risks to human health and the environment. The extent of environmental impact included upward of 1 million tons of contaminated sediments and soil over an area of roughly 100 hectares (AECOM, 2013). The Sydney Tar Ponds include three remediation sites including the Coke Ovens Site, the North Pond, and the South Pond. The Coke Ovens site is roughly 68 hectares in area 560,000…

The Cycles of Life By Max Hennemann Biogeochemical Cycles are the ways in which energy and elements flow throughout an ecosystem. These cycles are important because they transport the elements that we need to survive. The Hydrologic Cycle Also known as the Water Cycle Hydrologic Cycle Description The hydrologic cycle focuses on the movement of water throughout the environment. It depicts how H20 changes states in the cycle. Humans impact the hydrologic cycle when we consume, dam, and pollute…

water) became so dense that the calcium sulfate of the hard layer was precipitated. In the central deeper part of the basin, the last of the brine evaporated to precipitate more soluble sodium chloride (salt). Later, under the weight of overlying sediments, this salt flowed plastically upward to form salt domes. Before this happened, however, the Mediterranean was a vast desert 3,000 meters deep. Then, about 5.5 million years ago came the deluge. As a result of crustal adjustments and faulting,…
