Erosion

Phyllis and I worked together to artificially create weathering and erosion. What was supposed to be an informational video about science, Phyllis somehow transformed into a talk show about weathering and erosion. She inserted some very bad puns in the middle of serious information. She interviewed other students about their opinion on certain matters, which included their thoughts on the importance of erosion. It was unbelievably fun for a project that was intended to be boring. If the…

any place where forces, whether man-made or natural, have graded material to a slope too steep for its angle of repose. This may happen along an interstate highway, where a road crew has cut the slope too sharply, or on a riverbank, where natural erosion has done its work. (Slump involves movement along a curved surface, the upper part moving downward while the lower part moves outward) Slide is descending rock mass remaining relatively coherent, moving along one or more defined surfaces. A Rock…

progressive steps in cultivation”. (Cooper pg.145-146) She explores the idea that our use of the land in beneficial. In a way she sees it as a new representation of nature. This thinking helped push agriculture further, which eventually lead to soil erosion. This did a number on the soil because each planting process extracts nutrients from the ground to be used in the crop. As the soil deteriorates, so does the crop yield. It is important to note that this was a time before people truly…

that time, the area was a dry seabed spreading from horizon to horizon. The striking red rock features we see today would have been buried thousands of feet below you, raw material as yet uncarved. Then the landscape slowly began to change due to erosion (National Park Service). The national park lies on top of an underground evaporite layer or salt bed, which is the main cause of the formation of the arches, spires, balanced rocks, sandstone fins, and eroded monoliths in the area. ... Over…

experience more, exposing the South to enhanced rates of erosion. This is an issue because where land is sinking, there would be more exposure to erosion, henceforth changing the geomorphology in that area. Bird (1985) estimated around 70% of the world's sandy shorelines are being exposed to erosion. With the predicted sea level rise in the future, this will make extreme water levels higher and more frequent therefore causing high rates of erosion on beaches and dunes (Tebaldi, 2012). In this…

Introduction: Australia’s Great Barrier Reef (GBR), one of the world’s most precious marine ecosystems, has been deteriorating due to poor water quality (Kroon et al., 2016). One of the main reasons for this substantial decline in water quality over recent decades is agricultural runoff of nitrogen, pesticides/ herbicides and sediment (Figure 1). In fact, the water quality is most affected in the inshore areas in the southern and central regions near the most intensive agriculture. The impacts…

that the Great Lakes were once ancient riverbeds, providing the glaciers perfect pathways south. With each advance and retreat of the glaciers, the shape and water level of the lakes changed” (Ettema, 2010). The glaciers moved back and forth causing erosion that formed deep pits, which filled with meltwater before the glacier could move back. Figure 2 shows the movement of glaciers and how they shape the land. In this case, the glaciers rounded out the land and the meltwater would have…

polluted the soil and water systems in and around the fields. Water pollution exposed people and the environment downstream to the lethal chemicals being used in the farm fields. Pollution and tillage resulted in lower soil quality increasing topsoil erosion. Unintentional consequences in water use, soil deprivation, and chemical runoffs have had grave environmental impacts past of areas of cultivation and because of this the green revolution died down and more sustainable agricultural practices…

Chapter 5 explains different kinds of sediments, their origin, color and its contents. For example, biological sediments are white or cream color. Deep-sea clays are ranging from red to chocolate brown color because of the oxidation or rusting of iron within the sediments to form “iron oxide” which is basically rust and nodular sediments are dark brown and black. However boulders, cobbles, and pebbles made of better-quality particles which is sand, silt, and clay and they are defined by particle…

quality, reduce potential drainage of residual nitrogen to groundwater following the summer season, provide erosion prevention, carbon sequestration, bioenergy production and nutrient cycling. These crops cover crops protect water quality by recycling unused plant nutrients remaining in the soil from previous summer crop and work all winter to protect fields against wind and water erosion. They also improve soil for the next year’s crop by adding organic matter, suppressing weeds and providing…
