http://en.dzkx.org/article/doi/10.6038/cjg2024P0107 WebDec 4, 2024 · At the East Pacific Rise, the newly-formed ocean floor is more rigid. Cracks develop at the plate boundary. Tensional force causes normal faulting. The central block of the ridge sinks as downthrow because of gravity, forming the flat-bottomed rift valley. As plates move apart, cracks form.
