To what extent to you agree with the view that the hazards resulting from earthquakes and volcanic activity cannot be managed but merely adapted to. Earthquakes and volcanic activity are both nature disasters that human can’t control when or where it will happen and it may cause lots of death and economic loss. There is no way that we can stop it from being happened but we can definitely try to adapt it by many different ways. Firstly, volcanoes are found at destructive and constructive plate margins. At destructive plate margins, the oceanic plate goes under the continental plate due to it’s more dense, which is a process known as subduction.
| Since that time, some additional work has been done on veblens, and we understand them a little better. As I said, they are hills of sand or gravel that were deposited by relatively forceful upward flows of groundwater. The upward water flows had to have been with sufficient force to transport fairly coarse materials, in some cases rocks up to 3 or 4 inches in diameter. The only other geologic features that might be mistaken for veblens are glacial hills known as kames. However, kames consist of gravel and sand deposited by streams that flowed into holes in the glacial ice, depositing sediment in the holes.
("Geology," 2008) It resulted in the folding of the area and shortened the north/south length of the area by about 8.7 miles. (Jaritz, 2008) “Kata Tjuta, near the end line of this bulldozing movement, was tilted only by15 degrees. But Uluru was rotated and almost tipped over at a steep angle close to 90 degrees.” (Jaritz, 2008) The near vertical sediment layers evident within the formation of Ayers Rock are due to this major earth movement. The continuing formation of Ayers Rock occurred slowly after the Alice Springs Orogeny. About 65 million year ago, the climate of the area had become extremely wet, and this brought river sand, swamp deposits, and small traces of coal to the area.
He suggested that at the centre of oceans, molten material would rise from the Earth’s mantle, causing new sea floor to be created, pushing the ocean floor. He also suggested that there were ocean trenches where old sea floor would then go back into the mantle, and molten. He found that these ocean trenches, the deepest parts of the ocean, were very near continental plates. Hess theorized that the action of the sea floor spreading caused continents to move apart and so this being evidence for continental drift, showing why it happened. The evidence of sea floor spreading was further supported by Vine and Drummond, who studied the magnetic pattern of the sea floor.
When the glacier stopped, the sediments that had built up during the glacial movement are now dumped at the end of the glacier forming a moraine. The slow moving bottom of the glacier now plucks out loose rock material behind the moraine that is forming at the front (Charles Sturt University, Glacial Landforms and Formations, 2011 p2). This movement causes further material to be removed from the ground and moved to the front. Gradually, a large kettle is formed just behind the terminal moraine of the glacier. When the glacier melted the kettle filled with water and grew dude to further weathering.
Discuss the relative importance of two or more processes responsible for shaping the coast (such as marine erosion, transportation; deposition and land-based sub-aerial weathering, mass movement and runoff). (15 marks) The coast has many processes, which overtime will shape and change what it looks like. They are all responsible for shaping the land, they are all important in one way or another. The coastline is always changing. Marine erosion is a process which has a massive effect on the coastline.
When we refine or even dig up oil sands we produce harmful chemicals. Since Alberta oil sands are located near major rivers some of those chemicals end up in the rivers. The most famous case is with the Athabasca River, where the water is contaminated by many harmful chemicals. The Athabasca water ecosystem is slowly being poisoned and so are the people that use the water for their water supply. The oil sands maybe a large part of our social and economic structure, but they are slowly ruining our environment.
The Sierra Nevada create uplift of moist oceanic air masses and it rains. Much of the water reaches the San Joaquin valley but by the time the storms reach the eastern Sierra and Owens Valley, most of the water has been wrung from the clouds. The White and Inyo mountains, only twenty five miles east of the Sierra crest, are semi-arid. They suck the remaining water from the skies and by the time the air reaches the Saline and Death Valleys, it is bone dry. Such weather patterns have a great influence on the surface geology as well: erosion, deposition and chemical alternation take place rapidly in many parts of
The geology of Yosemite is mainly consisting of rocks and waterfalls. The main rocks are granitic rocks and metamorphic rocks. Ice Ages were the main causes for Yosemite Park or should I say California because the Ice Ages brought glaciers that carved out California. In Yosemite Park, it shows how the glacial have move and creating Yosemite Lake too. It created a lot of homes for the animals that are living in the park and became big attractions for visitors all around the world.
Due to, again warmer temperatures both maximum and minimum we are seeing ice melt. “Data from NASA's Grace Satellites show that the land ice sheets in both Antarctica and Greenland are losing mass. The continent of Antarctica has been losing more than 100 cubic kilometers (24 cubic miles) of ice per year since 2002” (Global Climate Change: Key Indicators, 2014). Warming air and land temperatures seem to be causing the land ice and artic ice to melt. Where is all this melting ice going?
