Describe and discuss the sea level changes with respect to the continents during the Cretaceous Period. What caused
this event? What will be an ideal response?
The sea level rose with respect to the land during the Cretaceous. This transgression was
caused by increased volcanism and accelerated seafloor spreading along mid-ocean ridges,
which resulted in the displacement of waters upward onto the continents as Pangaea
continued to rift.
