Findings suggest that the slowdown in seafloor spreading caused deepening of ocean basins, affecting global sea levels over millions of years. Tectonic Activity and Ocean Basin Deepening According to ...

This reduction, mostly resulting from a global slowdown in seafloor spreading, caused ocean basins to deepen. ... Evidence is building that people were in the Americas 23,000 years ago.

Geology postdoctoral researcher Jingchuan Wang said, “This thickened area is like a fossilized fingerprint of an ancient piece of seafloor that subducted into the Earth approximately 250 million years ...
