Mt Cook/Aoraki formation Vinoth Loganathan New Zealand is a nation which ‘straddles’ between two tectonic plates, the indo-Australian and the Pacific. The location from the South Isle is to the south of both Australia and South Africa, this really is a major factor to the geological process of weathering because it makes Mt. Prepare subject to the westerly winds.

MT Prepare is situated in the Southern Alps between the two tectonic discs mentioned above. Its current elevation is now stated at a few, 753 metres making it the tallest mountain in Australasia.

The mountain itself has been formed simply by three key geological procedures, one inside: tectonic beneficial and 2 external: weathering and erosion. Internal: 1 ) Tectonic Outstanding Mt. Prepare food was formed by internal means of orgenic tectonic uplifting, in which two discs collide and one menu increases in elevation as well as the opposite dish decreases. Even so Mt. Prepare formed differently compared to different mountains. This is due to both tectonic plates having landmass at the top and the plates meeting for different perspectives. The movement occurring is grinding which will pushes up land mass (Mt.

Cook) and provides an impressive transform fault. Present charge of uplift is five to ten mm a year but this really is easily countered by weathering and erosion. Evidence of this kind of uplift is definitely apparent for the mount for the south ridge specifically the Endeavour lacet fold in which sand, dirt and silt has been flattened and cracks forming vertical beds of silt and sandstone. Overall the tectonic uplift of Mt. Cook over the past 2 to 3 million years could have been about 20 kms but enduring and erosion have very easily countered it. Westerly Gusts of wind External 1 ) Weathering Mt.

Cook continues to be shaped simply by powerful causes of enduring. Mt Make is susceptible to high amounts of weathering because of its height and location. Mt Cook is located southern region of Quotes and South Africa making it the first significant barrier towards the powerful westerly winds the ‘roaring forties’. Due to the wind Mt. Prepare food is be subject to various several types of weathering just like freeze thaw weathering. If the wind reaches the The southern area of Alps the air rises and drops rain on Mt. Cook. When the water extends to the hill it lands in a bust, it then interrupts freezes and expands making the fracture bigger.

The procedure repeats and weathers the mountain. This process occurs all around the mountain speedily due to typically temperature alter. This process likewise occurs a lot on the peaks on the mountain being exactly why the peaks are so ‘sharp’. 2 . Chafing The wind and rain impacting on Mt. Prepare is a significant cause of chafing. Rain and wind both equally use the law of gravity to essentially remove the ‘loose rock’ with the mountain. Rainfall does it simply by ‘washing’ that off and wind will it by ‘blowing’ it away. There is significant evidence that substantial erosion has took place on Mt. Cook.

This really is located with the valleys from the Southern Alps. Large lake beds made up of of ‘eroded scree’ and gravel. Also multiple snow such as the hooker glacier will be carrying eroded debris complementing the rock Mt. Prepare food is made up of. Enduring and chafing have contributed to the formation of Mount Make by healthy diet it. The design of Mt. Cook is usually wide at the end but lanky at the top this is because the higher you go the more weathering and chafing occurring. And so in conclusion Mt. Cook has become formed by multiple geological processes and it is continuing being formed this kind of present grow older.
