GLG-F108: Geology & Geopolitics: The Silk Road Professor Y. Dilek Fall 2010 Homework #3 Due: 07 Sept 2010 READING ASSIGNMENT (1) The Collision Between India & Eurasia, P. Molnar & P. Taponnier, Scientific American (2) The flow of the continents & a change in the weather, S. Lam & D. Sington, Princeton Univ. Press Please type your answers in complete and succinct sentences on a separate sheet, and make sure to spell-check your entire text before getting a final printout for submission. The eight questions below are based on the paper by Molnar & Taponnier: 1. To what basic cause can be attributed the great geological and topographical diversity of the Himalayas, Tibet, and western China? 2. How far north has the Indian subcontinent moved since its collision with Asia? 3. In what way is this continued motion responsible for the present earthquake activity in and around Asia? 4. What are some of the greatest faults in the region? 5. What happens when two continental plates collide?

Unformatted text preview: 6. How do rocks called ophiolites define a suture between two continents? 7. What hypotheses have been put forward to explain how the continued northward push of the Indian subcontinent has been accommodated in the region? (Hint: Think about what kind of deformation and faulting patterns have been documented in Asia). 8. How can we test the hypothesis suggesting that the Indian-Asian convergence is indeed associated with large-scale lateral displacements in China? The three questions below are based on the paper by Lam & Sington: 9. According to Philip Englands model, what geological processes have played a major role in a sudden rise of the Tibetan Plateau after the collision of India with Eurasia? 10. How can mountains affect the weather patterns on continents and the global climate change? 11. How can scientists show that the nearly 5-km-high Tibetan Plateau was once much lower in elevation?...
