Sea level fluctuated several times during the Paleozoic.Which of the following is not a representative factor for sea level rise in the Paleozoic?
A)Melting of continental glaciers.
B)Ocean basins stood high on the asthenosphere due to active seafloor spreading.
C)Ocean basins stood high on the asthenosphere due to slow but continuous seafloor convergence.
D)The breakup of the Precambrian supercontinent.

Question

Quizplus · Accepted Answer

Slow but continuous seafloor convergence would result in the contraction of ocean basins, which would decrease sea level rather than causing it to rise. Melting of continental glaciers (A), active seafloor spreading (B), and the breakup of the Precambrian supercontinent (D) are all factors that could lead to sea level rise in the Paleozoic.
