The reading and the lecture are both about the mass-extinction event 200 million years ago. Scientists have many theories about this event. The author of the reading has three reasons for it. The lecturer also has three reasons that disagree with the author of the reading.
First, the author argues that one of the reasons that account for mass-extinction is declining sea levels. The article mentions that when sea level falls, the habitats of the ocean population and land species are destroyed. This specific argument is challenged by the lecturer. She claims that the falling of the sea levels is gradual. It takes a long time to fall completely. Hence, declining of sea level is not an accurate reason. To add more, the species in the shallow part have adapted to this event over a long period time.
Moreover, the writer suggests another reason and that is massive climate cooling by volcanoes. In the article, it is said that the volcanoes made enormous amounts of sulfur dioxide and it makes climate temperature low. The lecturer, however, rebuts this by mentioning that sulfur dioxide can cause the low temperature climate, however, So2 can stay in the atmosphere for a short period of time. Furthermore, So2 is mixed with water and can fall out as rain. Thus, this cannot be a solid reason for the extinction.
Lastly, the author posits that the other cause is the amount of soil and crushed rock caused by an asteroid strike. Moreover, it is stated in the article that an asteroid impacts at the end of the triassic period and it blocks the sunlight. In contrast, the lecturer’s position is people have not found any asteroid crater. In addition, the crashing of an asteroid happened a long time ago before the world in the triassic period. Thus, this is an impossible theory.
