tpo 39 mass-extinction
The material discusses several theories that might cause a mass-extinction at the end of the Triassic period. While the reading looks at the topic from one perspective, the listening challenges certain points outlined in the reading passage.
Firstly, the reading details specific points regarding this topic. Namely, sea-level fluctuation might cause this extinction. Next, global cooling due to volcanic activity might involve in a mass-extinction. Finally, an asteroid hit the Earth might cause big destruction.
Conversely, the lecture challenges the points. One specific contradiction is coastal and shallow-water habitats usually are adapted to environmental changes; furthermore, the sea-level fluctuation was quite gradually, so sea level should go down much more suddenly to have any negative impact on the environment. In addition to that, sulfur dioxide that causes global cooling after any volcanic activity stay for a short period, becasue it could be cleared out by combining with water and fall as rains. As a result, sulfur dioxide should stay long enough to cause mass-extinction. One final point, there are no asteroids craters dated back when this mass-extinction happened; on the other hand, there are other craters that dated back 12 million years before the extinction occurred.
