the mass extinction
The listening and the reading materials have a conflict of opinions about some explanations of the mass extinction that happened at the end of the Triassic period. The writer in the reading passage explains three theories for this event. On the other hand, the lecturer believes that these theories are not good explanations.
First of all, the professor in the lecture makes it clear that the sea levels had a fluctuation at that time, but this happened during a long time. Thus, if the sea levels decreased gradually, it cannot be a reasonable theory in the widespread area. In contrast, the writer explains that this event has a major impact on the food chains and it caused the mass extinctions.
Second, the professor describes that if volcanoes released SO2, it had the influence of the short time and the atmosphere clear out of this gas. In addition, the SO2 combined with the water and went back to the earth as the rain. By contrast, the author holds the opposite view that this issue has an impact on the climate and led to the extinction.
As a final point, the speaker believes that an asteroid strike does not have a role for this event because it happened 12 million years before this extinction so that it cannot play a role in this extinction. On the contrary, the writer disagrees with the lecture’s opinion. It is believed that when the asteroid collided with earth, it blocked sunlight for a long time that led to the death of the plants and animals.
