summarize the points made in the lecture, being sure to explain how they challenge the points that several reasons to explain the mass-extinction mentioned in the reading passage
In the reading passage, the author discusses several possible explanations to account for the mass-extinction of many living species, while the lecture claims that what the passage state is not convincing and disputes those ideas presented in the passage with several proofs.
Firstly, according to the reading passage, on theory is about the decline of sea levels contributed to shallow ocean populations and costal lan species are destroyed so that it would have a profound effect on found chain. On the contrary, the professor argues in the lecture that the descent of the ocean takes about several million years and the costal ecosystem had been adaptive to this gradual change. Gradual transform would not cause a widespread and negative impact on species.
In addition, the statement in the reading material indicates that the volcanic activity at the end of the Triassic period would release large amounts of sulfur dioxide that cause a lowering in global temperatures. In this case, climate change could let to the mass-extinction. In contrast, the professor points out that sulfur dioxide that liberate by volcano could continue only a short period of time before disappearing because it could combine with water and fall into the ground as rain. Therefore, it is not likely caused by climate cooling.
Finally, the author of the reading claims that there would be a asteroids collide with Earth and thrown up debris into the atmosphere, which could block out sunlight for several month or even a longer time. With blocking sunlight for a long time, many animal species and plants would die. However, the speaker argues that scientists barely found any crater that hit by asteroids in the Earth. The only crater occurred about 1200 million years ago before the mass-extinction happened.
