Webseafloor spreading, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from … WebHot mantle from the two adjacent cells rises at the ridge axis, creating new ocean crust. The top limb of the convection cell moves horizontally away from the ridge crest, as does the new seafloor. The outer limbs of the convection cells plunge down into the deeper mantle, dragging oceanic crust as well. This takes place at the deep sea trenches.

Web4 apr. 2024 · The seafloor spreadingtheory is one hypothesis introduced to suggest a mechanism of controlled CO2 levels in the atmosphere, causing the observed variations between warm CO2-rich greenhouse intervals and cold CO2-depleted global cooling intervals. This theory focuses the control of CO2 levels on plate tectonic processes. WebB. It has only recently been discovered that tectonic plates are closely fitting rather than loosely constructed, as geologists previously believed. C. The hot-spot trails formed by volcanic island chains indicate the positions of tectonic plates as far back as the present ocean basins have existed. D.
