Question
Chapter 29, Problem 6RAT
To determine
The correct option for the statement “The paleozoic experienced several fluctuations in sea level. When sea level rises”.
Expert Solution & Answer
Answer to Problem 6RAT
The correct option for the statement “The paleozoic experienced several fluctuations in sea level. When sea level rises” is option (a).
Explanation of Solution
The palaeozoic era began about 543 million ago and lasted with 295 million years. In this era formation of Earth’s ocean started.
The paleozoic era is the time when sea level rose and fell worldwide. This allowed sea water to cover different continents and progression and diversion of sea water life. In this time, different new species were found, which increased the diversity of marine life.
Thus, we can say at the time of the Paleozoic era there are several fluctuations were occurred in sea level, when sea level raises shallow seas to cover the continents.
Conclusion:
Therefore, the correct option for the statement “The paleozoic experienced several fluctuations in sea level. When sea level rises” is option (a).
