How does sea spreading affect global sea level?

Seafloor spreading determines plate motion around a midocean ridge. Midocean ridges are always plate boundaries. Since many plates, such as the North American ... Aug 1, 2009 ... Our models show that a high average seafloor spreading rate of 92 mm/a in the Early Cretaceous that decreased to 60 mm/a during the Tertiary, ... Mar 30, 2016 ... The magmatic, tectonic, and hydrothermal processes forming the oceanic crust along mid- ocean spreading centers are strongly modified at ... The Earth's magnetic field has north and south poles. Geophysical observations suggest that the Earth's magnetic field is generated within the liquid of the ... Because of this, the youngest sea floor can be found along divergent boundaries, such as the Mid-Atlantic Ocean Ridge. The spreading, however, is generally not ... Mar 2, 2017 ... Geological Survey of Canada geophysicist Lawrence Morley was one of the first to have the “eureka” moment that put all the pieces together when ... Oct 2, 2015 ... Mid-ocean ridge volcanism and extensional faulting are the fundamental processes that lead to the creation and rifting of oceanic crust, ... Sep 25, 2008 ... Muller, R.D., M. Sdrolias, C. Gaina, and W.R. Roest 2008. Age, spreading rates and spreading symmetry of the world's ocean crust, Geochem. Sep 3, 2022 ... This hypothesis traces oceanic crust from its origin at a mid-ocean ridge to its destruction at a deep sea trench and is the mechanism for continental drift. Mar 3, 2025 ... Depending on what study you look at, the seafloor spreading can make everything from 100m to over 1000m of sea level change.
