'Mt Cook Formation\r'

'Mt defecate/Aoraki system Vinoth Loganathan New Zealand is a country which ‘straddles’ surrounded by both archiarchitectonic plates; the indo-Australian and the Pacific. The location of the South Island is south of both(prenominal) Australia and South Africa; this is a major contri neverthelessor to the geologic surgery of weathering because it makes Mt. ca-ca heart-to-heart to the westerly winds. MT Cook is laid in the Southern the Alps between the two tectonic plates mentioned above. Its current bill is now stated at 3,753 meters qualification it the tallest mountain in Australasia.The mountain itself has been organize by three main geological processes; one internal: tectonic excite and 2 external: weathering and erosion. Internal: 1. tectonic Uplifting Mt. Cook was form by the internal process of orgenic tectonic discovering, where two plates collide and one plate increases in elevation and the opposite plate decreases. up to now Mt. Cook formed dif ferently compared to another(prenominal) mountains. This is due to both tectonic plates having land mass on the top and the plates meeting at different angles. The movement occurring here is cranch which pushes up land mass (Mt.Cook) and creates a transform fault. Present rate of collect is 5-10 mm a year scarce this is easily countered by weathering and erosion. Evidence of this uplift is apparent on the mount on the south ridge specifically the campaign col fold where sand, mud and back up has been folded and fractures forming vertical beds of silt and sandstone. Overall the tectonic uplift of Mt. Cook over the past 2 to 3 million eld could have been up to 20 kilometres but weathering and erosion have easily countered it. prevailing westerly Winds External 1. Weathering Mt.Cook has been shaped by effective forces of weathering. Mt Cook is subject to blue amounts of weathering due to its height and location. Mt Cook is located south of Australia and South Africa making it the first real barrier to the healthy westerly winds the ‘roaring forties’. collectible to the wind Mt. Cook is subject to assorted different types of weathering such as occlude thaw weathering. When the wind reaches the Southern Alps the air rises and drops rain on Mt. Cook. When the water reaches the mountain it lands in a crack, it therefore freezes freezes and expands making the crack bigger.The process repeats and weathers the mountain. This process occurs all over the mountain apace due to often temperature change. This process also occurs a lot on the peaks on the mountain being the reason why the peaks are so ‘sharp’. 2. wearing away The wind and rain affecting Mt. Cook is a significant cause of erosion. precipitate and wind both use gravity to essentially remove the ‘loose wave’ of the mountain. Rain does it by ‘washing’ it bump off and wind does it by ‘blowing’ it off. There is significant evide nce that substantial erosion has occurred on Mt. Cook.This is located at the valleys of the Southern Alps. gravid river beds do up of of ‘eroded astragal’ and gravel. Also nonuple glaciers such as the hooker glacier are carrying eroded junk matching the rock Mt. Cook is made up of. Weathering and erosion have contributed to the formation of Mount Cook by organization it. The shape of Mt. Cook is wide at the bottom but skinny at the top this is because the higher you go the more than weathering and erosion occurring. So in shutdown Mt. Cook has been formed by multiple geological processes and is continuing to be formed this present age.\r\n'
