▶ Your Answer :
Both the lecture and the reading hold different
positions, respectively, on the issue of the cause of K-T extinction. The
lecture's argument is formed around many points that are in direct contrast to
the material in the reading passage.
First, the lecture argues that K-T extinction was caused by
asteroid collision rather than a
large amount
of volcanic activities. According to the lecture, massive craters in India
indicate the evidence of asteroid collision. This rebuts the reading which
suggests that many volcanic activities shown in the case of the Deccan traps in
India are primary cause of K-T extincion extinction.

Second, in to the lecture, dust
and ash collected from K-T extincion extinction
period provide essential evidence of the fact that there were no such volcanic
activities in that time. Since While volcanic
activities do not release irridium/iridium 이라고도 표기합니다 ^^>
dust particle, and dust
and ash found in that period contains irridium/iridium
dust particles, this shows that K-T extinction was not resulted from
volcanic activity. In fact, asteroid contains high concentration of irridium/iridium composition. <첫 번째 이유와 대응됩니다> Therefore,
this challenges the reading's point that volcanic dust and ash blocked out the
sun and this leads itself to the climate changes which made a lot of species
extinct.
Lastly, the lecture concludes by contending that K-T
extinction and volcanic activity did not occured occur at the same time. According to the professor, volcanic
activities took place millions of years, however, K-T extinction occured
occurred just few thousand years ago. This shows
that they did not occured occurred simultaneously.
Therefore, this disproves the reading's claim that K-T extinction and massive
volcanic activities are deeply related to each other.
