Mt Cook Formation

Mt earn/Aoraki formation Vinoth Loganathan New Zealand is a country which straddles between cardinal architectonic plates the indo-Australian and the Pacific. The location of the South Island is south of both Australia and South Africa this is a study contributor to the geological process of weathering beca delectation it makes Mt. stimulate subject to the westerly winds. MT Cook is situated in the Southern Alps between the two tectonic plates mentioned above. Its current height is now stated at 3,753 meters making it the tallest jackpot in Australasia.The mountain itself has been organize by three important geological processes one cozy tectonic turbulenceing and 2 foreign weathering and erosion. Internal 1. Tectonic Uplifting Mt. Cook was formed by the internal process of orgenic tectonic uplifting, where two plates collide and one plate increases in elevation and the opposite plate decreases. However Mt. Cook formed differently comp bed to other mountains. This is ascr ibable to both tectonic plates having landmass on the go and the plates meeting at different angles. The movement occurring here is grinding which pushes up land mass (Mt.Cook) and creates a transform fault. Present rate of uplift is 5-10 mm a year but this is easily countered by weathering and erosion. show up of this uplift is apparent on the mount on the south continue specifically the Endeavour col fold where sand, mud and silt has been folded and fractures forming erect beds of silt and sandstone. Overall the tectonic uplift of Mt. Cook over the last(prenominal) 2 to 3 million years could have been up to 20 kilometres but weathering and erosion have easily countered it. Westerly Winds External 1. Weathering Mt.Cook has been regulate by powerful forces of weathering. Mt Cook is subject to high amounts of weathering due to its height and location. Mt Cook is located south of Australia and South Africa making it the first significant barrier to the powerful westerly winds th e roaring mid-forties. Due to the wind Mt. Cook is subject to various different types of weathering much(prenominal) as freeze thaw weathering. When the wind reaches the Southern Alps the circularize rises and drops rain on Mt. Cook. When the water reaches the mountain it lands in a crack, it and so freezes freezes and expands making the crack bigger.The process repeats and weathers the mountain. This process occurs all over the mountain rapidly due to often temperature change. This process also occurs a round on the peaks on the mountain being the reason why the peaks are so sharp. 2. Erosion The wind and rain affecting Mt. Cook is a significant cause of erosion. Rain and wind both use gravity to essentially remove the loose quake of the mountain. Rain does it by washing it off and wind does it by blowing it off. There is significant indorse that substantial erosion has occurred on Mt. Cook.This is located at the valleys of the Southern Alps. expectant river beds made up of of eroded scree and gravel. Also multiple glaciers such as the hooker glacier are carrying eroded debris matching the rock Mt. Cook is made up of. Weathering and erosion have contributed to the formation of surface Cook by shaping 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 weathering and erosion occurring. So in conclusion Mt. Cook has been formed by multiple geological processes and is continuing to be formed this pass on age.
