From what I understand global contraction, or the slow shrinking and deformation of the Earth’s crust, was one of the dominant ideas in geology prior to the development of plate tectonics. I know it has been ruled out in favor of plate tectonics, but I recently read that it does seem to have played a role in shaping features on other bodies in the solar system like Mercury and the moon. I’m curious if global contraction is still thought in modern geology to have had any kind of effect on Earth’s crust in the present or past?
