Web29 okt. 2024 · Seafloor spreading contributes to continental drift by the creation of new landmass at the locations in mid-ocean ridges where tectonic plates diverge. Over time, … WebThe Red Sea Rift was formed by the divergence between the African Plate and the Arabian Plate. The rift transitioned from a continental rift to an oceanic rift. [1] Magnetic anomalies suggest that the spreading rate on either side of the Red Sea is about 1 cm/year. The African plate has a rotation rate of 0.9270 degrees/ Ma, while the Arabian ...
WebSeafloor Spreading is the usual process at work at divergent plate boundaries, leading to the creation of new ocean floor. As two tectonic plates slowly separate, molten material rises up from within the mantle to … WebThe process of sea-floor spreading created the lithosphere under the Atlantic Ocean.

Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this magma has created high ridges on the ocean floor over millions of years. However, the seafloor is destroyed in …
WebMaps and other data gathered during the war allowed scientists to develop the seafloor spreading hypothesis. 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. Seafloor Bathymetry
