Geology Field Work Essay

- The area of Kuncizzjoni and Fomm ir-Riħ is found at the edge of the Victoria lines. It lies between a system of horst and graben. Kuncizzjoni is uplifted on a horst feature, which carries the Victoria lines that are built across the Great Fault. Alluvial deposits are found in the valleys due to the percolation of the rain water down to the lowest plains, and because of the high percentage of clay found in the soil. Clayey soils made the valley an ideal place to terrace fields for agricultural purposes....   [tags: Geology ]

Historical Geology Of The Southwest Landslide Essay

- Matthew Sewell 6/9/15 Historical Geology 204 Historical Geology Final 1.) There are three clear landslides; the southwest landslide is stream-laid sand and gravel from the quaternary that was located on a steep slope resulting in gravity pulling sediments down the steep slope. The northeast landslide appears to be tuff sediments that have fallen upon biotite-quartz diorite rocks. The northwestern landslide is the largest of the landslides. The landslide occurred just south of the creek; erosion must have lowered the creeks elevation creating a steep decline resulting in Bena gravel to fall....   [tags: Volcano, Plate tectonics, Geology, Volcanology]

Essay about Geology: The Study of the Earth

- Erosion occurs when wind or water blow/wash away the topmost fertile layer of soil. As fertile land loses its fertility due to soil erosion, it is difficult to grow crops on eroded lands. Apart from affecting crops, erosion also weakens land, causing buildings to collapse. Soil erosion can be prevented by planting windbreaks. Windbreaks are lines of planted bushes and plants that hold soil firmly with their roots and prevent it from being washed away. Other methods include terracing, in which level plains are cut on hillsides and crops are grown on these plains....   [tags: Geology ]

Essay on Rocks and Dates Geology Analysis

- The Grand Canyon is a wonderful place to gain a sense of how old the earth really is because of the ability to date the layers of rock in the canyon. The Rocks exposed in Grand Canyon are truly ancient, ranging from 1840 million years old or 1.84 billion years old (to 270 million years of age. (Beus, and Morales, 2003). While the Grand Canyon is not old in comparison to much of the earth, it is considered young earth because it was slivered by an ie in the last six million years. This gives the rocks in the Canyon Ice age fossils and new deposits, in the grand scheme of things....   [tags: grand canyon, rock layers, geology]

The geology of Sicily Essay

- The geology of Sicily has a long and complicated history originating during the Mesozoic. The features that compose the present-day Mediterranean is a result from two major processes: the subduction of the African plate underneath the Eurasian plate, and the closure of the Mediterranean Sea. Deposits of carbonate sediment and marine organisms that were deposited from the Tethys Sea (Late Triassic to Early Cretaceous), make up the oldest exposed rocks of western Sicily. During this time, the area’s structural setting was largely dominated by transtentional plate movements which resulted in fault block morphologies with alternating horst and graben structures and east-west trending normal faul...   [tags: mediterranean sea, african plate]

Psychology and Geology Essay

- Psychology is the study of the mind and the behavior of mammals. Geology is a science that deals with the history of the earth and its life, recorded in rocks. The earth is consistently moving its tectonic plates. Therefore, there may be over 100 earthquakes a day; most of these earthquakes go unnoticed by humans on the crust of the earth. Other earthquakes for example, the one in 2011 located in Japan and the Loma Prieta earthquake of 1989 (Earth- Marshak). Unfortunately, many people died in horrific ways during these deadly earthquakes, leaving thousands diagnosed with psychological disorders such as, Posttraumatic Stress Disorder and Specific Phobias directly related to the natural envir...   [tags: Post Traumatic Stress Disorder]

Impact of Fire on the Geology of Soils Essay

- Fires are an important and healthy process in many ecosystems. The lack of fires can cause new plant communities to invade an area . The regular occurrence of fires can keep one plant community dominate, like oak savannas. Fires can leave burnt sticks the size of trees and clumps of charcoal where bunch grass use to grow, but not for long. An area that was burned will re-grow, grasslands will be green the next growing season and forests will typically show new growth soon after. Somewhere in the process of a fire the soil it travels over is effected....   [tags: Wildfires and Soil Geology]

Essay on Geology of Mars

- Geology of Mars Mars is the planet that is the closest geologically to our own. Still we know little about the planet. All the information that we have is from what we see. We can speculate about the geology of the planet but we will never know for sure what the planet is really made of until we physicallygo there. The information is all from NASA sites or NASA related sites. Mars' red color leads us to believe that the planet has large amounts of iron. This red color is the only color that is on the surface besides the poles....   [tags: Papers]
