Uplift due to mantle upwelling often precedes continental rifting as the mantle's movement begins to thin and stretch the continental lithosphere. This process can eventually lead to the formation of a rift valley. If rifting continues, it can progress to the stage of seafloor spreading, where new oceanic crust is formed, further separating the continental fragments.
