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 ...
Results of seafloor spreading: Mid-ocean ridges: submarine mountain ranges along divergent boundaries in oceans; Mid-Atlantic Ridge: center of Atlantic Ocean
Download presentation. Presentation on theme: "Plate Tectonics and Seafloor Spreading"— Presentation transcript: 1 Plate Tectonics and Seafloor Spreading. 2 Discovery of Subsea mountain ranges. led to theories of: Plate Tectonics and Seafloor Spreading. 3. 4 Development of Plate Tectonics Theory.
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.
