Question

which of the following statements correctly describes the trends seen in the data?
a the highest sea level occurred in the triassic period.
b the lowest sea level occurred during the paleogene period.
c the first rise in sea level occurred during the cretaceous period.
d sea level decreased from the beginning of the triassic period to the end of

Explanation:

• Option A: The highest sea level is not in the Triassic period. By observing the graph, we can see that the sea - level in the Cretaceous period is higher than that in the Triassic period.
• Option B: The lowest sea level is not in the Paleogene period. The graph shows that the sea level in the Paleogene period is relatively high compared to some earlier periods.
• Option C: The first rise in sea level is not in the Cretaceous period. There are rises in sea level in earlier periods (such as the Cambrian - Ordovician transition).
• Option D: By looking at the graph, from the beginning of the Triassic period to the end of the Triassic period, the sea - level curve is moving towards the "Falling" direction.

Answer:

D. Sea level decreased from the beginning of the Triassic period to the end of
