Question

Zagros Mountains and the Arabian Plate (16 points) Open and view the Plate Tectonic Animation PowerPoint document in the Introduction to Geology and Geophysics folder on the L drive. The slides show a simplified plate tectonic evolution of Earth in the Mesozoic and Cenozoid. 1. What geographic feature was directly to the west of the Arabian plate between 200 Ma (Jurassic) and 30 Ma (Oligocene)? ("Ma" means millions of years before present.) (1 point) 2. a) By 80Ma in which hemisphere was the UAE? (1 point) b) What was the UAE's range of latitude from 80Ma to OMa? (If you are unsure of the latitudes check the “Present Day" slide.) (3 points) 3. Thick sandstone tends to indicate ancient high mountains, rainy, and sometimes cool climates. Limestones tend to indicate a warm climate in low- lying coastal areas that are easily flooded during times of high sea level. Do you think that sandstone or limestone is more abundant in 200 to 120 million year old rocks in the subsurface of UAE? (1 point) 4. How long ago did the Arabian Plate and Africa finally split? (2 points) 5. When did the Arabian plate collide with Asia to form the Zagros Mountains? (2 points)

Explanation / Answer

Answer4- The Arabian plate and Africa split approximately 25 million years ago, which resulting in the closure of the subducting Tethys sea in the northeast.

Answer5- 25-23 million year ago Arabian plate collide with Asia to form the Zagros mountain because many cities are in danger.
