1)In 2005 the Chinese Academy of Sciences announced the most accurate measurement of Mt.Everest to date at 8,844.43 m. In 1856 however, the Great Trigonometric Survey announced that PeakXV (later renamed to Mt. Everest) was the highest peak in the world at 8,839.8 m. Let’s assume that these measurements are both accurate. If we assume, that as the Indian Plate crashes into the AsianPlate, half of the Indian Plate’s mass goes into the Earth to be recycled, and the rest goes into buildingthe Himalayas, how fast is the Indian plate moving? Express your answer in mm/year.
2)Before Pangea began to break up, the peninsula of India would have been connected to modern day Mozambique, which today are approximately 5000km apart. Using your answer from part 1) calculate how long ago Pangea began to break up. Show your work.
3)Today we know that Pangea actually began to break up ~175 million years ago. Does your answer agree with part 2)? If no, give a possible explanation as to why not and describe any assumption you may have made in part 2)
