How does seafloor spreading continental drift
WebIt is a place of earthquakes and volcanos. Seafloor spreading helps explain continental drift in plate tectonics. At oceanic trenches, seafloor crust slides down and under continental crust. Earlier theories (e.g. by Alfred Wegener) of continental drift were that continents ' plowed ' through the ocean. The modern idea is that the ocean floor ... WebJun 30, 2015 · Seafloor spreading adds material to oceanic plates, causing the oceanic plate to come into contact with other plates but not necessarily causing those affected plates to "drift".

WebMay 20, 2024 · According to this theory, Earth’s crust is broken into roughly 20 sections called tectonic plates on which the continents ride. When these plates press together and then move suddenly, energy is released in the form of earthquakes.

In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them. What is the evidence for sea-floor spreading? shari mccollough silkiesWebA profound consequence of seafloor spreading is that new crust was, and is now, being continually created along the oceanic ridges. This idea found great favor with some scientists who claimed that the shifting of the continents can be simply explained by a large increase in size of the Earth since its formation. shari mcburney deep seed doulaWebFeb 19, 2024 · Plate Tectonics.
