TPO 39
At the end of the Triassic period 200 million years ago, there was a mass-extinction event that caused the extinction of more than half of all living species. It was this extinction event that allowed dinosaurs to become the dominant species for the next 145 million years. We do not know exactly what happened that eliminated so many species in a relatively short period of time, but there are several possible explanations.One theory involves the decline of sea levels. Near the end of the Triassic period, sea levels were fluctuating. When sea levels fall, the habitats for ocean populations that live in the shallows and land species that live on the coast are destroyed. The destruction of coastal and shallow-ocean species would have had a profound effect on food chains worldwide, leading to mass extinctions.Another theory involves massive climate cooling. The end of the Triassic period was marked by widespread volcanic activity. The volcanoes released large amounts of sulfur dioxide (S02). A rise in atmospheric S02 is known to cause a lowering in global temperatures. Such climate change could have devastated many species and led to the extinctions.The third theory involves an asteroid strike. Asteroids (objects from outer space) occasionally collide with Earth. When an asteroid hits Earth’s surface, it often displaces large amounts of soil and crushed rock, leaving behind a depression, or crater. The displaced debris is thrown up into the atmosphere where it can block out sunlight for many months or even a few years. A sufficiently massive asteroid impact at the end of the Triassic period may have blocked sunlight long enough for most plants to die and many animal species to then starve.
The reading passage talking about the massive extinction of more than half of all living species in a short period of time. But the professor claimed that assessment, he states three reasons which he considered it more accurate at that time. He cast a doubt about this theories because of numerous reasons.
Firstly, according to the first theory discussed in the allegation of the script that the sea level were fluctuating occurred that impact most of the living species. For instance, the shallow and coastal ocean species by getting destroyed. In contrast to the narrator who revealed that fluctuate happened definitely but was gradually changed according to the eco-system adaptation changes. Moreover, it should happened suddenly to lead to this massive extinction.
Second, according to another theory poses in the essay that the climate changes led to global cooling. Especially at the end of Triassic period when volcanic activity marked. The by product from the volcanos was huge amount of the sulfur dioxide and that affect the living of some species. The lecturer controvert this concept because he believes that the sulfur dioxide cleared out by binding to water and becoming rain.
Third, about the last theory the essay claimed that the Asteroid phenomena affect this species to live by making hug hall and block-out the sun light. Additionally, that impact species by ending with death and starvation for most of them. The aerator oppose that, he claimed that there was not any Asteroid at that time because Asteroid crashed with the earth many years before the extinction.
