28 Απρ 2020 · Seafloor spreading helps create mid-ocean ridges, giant underwater mountain ranges that develop where tectonic activity is driving plates apart from each other. This lovely map highlights where tectonic plates are separating at mid-ocean ridges.

20 Νοε 2017 · 2) Evidence from seafloor spreading and magnetic stripes on the ocean floor support the theory of plate tectonics, where new ocean crust forms at mid-ocean ridges and spreads outward as the plates move.
30 Ιουν 2012 · 1. The document discusses sea-floor spreading, which is the process where new oceanic crust forms at mid-ocean ridges as tectonic plates move away from each other. 2. Evidence that supports sea-floor spreading includes magnetic stripe patterns in the ocean floor and samples from ocean crust that show it is younger near ridges and older further ...
Evidence for Seafloor Spreading In 1960, Harry Hess studied Wegener’s theory. Hess proposed the radical idea that the ocean floors move like a conveyer belt , which in turn move the...
Discovery of Subsea mountain ranges led to theories of: Plate Tectonics and Seafloor Spreading
Theory of Plate Tectonics Plate Boundaries Convergent Boundaries When an oceanic plate converges with a continental plate, the denser oceanic plate is subducted. Oceanic-continental convergence produces a trench and a series of volcanoes along the edge of the continental plate.
