WebbSeafloor 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 …
Webb22 mars 2012 · In 1960, Harry Hess proposed that the movement of the continents was a result of sea-floor spreading. He hypothesized that the sea-floor was spreading from vents in the Great Global Rift, where hot magma oozed up. As the magma cooled it forced the existing sea-floor away from the Rift on either side. What Goes On At Mid-Ocean Ridges? … how to send money to familyWebbSeafloor spreading is a natural geologic process that separates large tectonic plates from the Earth’s lithosphere. The evidence behind seafloor spreading supports continental drift theory. This evidence is provided from magnetic stripes as well as molten material. Get started with your UPSC preparation today how to send money to palawan expressSeafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. The motivating force for seafloor spreading ridges is tectonic plate slab pull at subduction zones, rather than magma pressure, although there is typically significant magma activity at spreading ridges. Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called rid… how to send money to fbop inmateWebbThis process, called sea-floor spreading, continually adds new material to the ocean floor. Scientists have found strange rocks shaped like pillows in the central valley of mid-ocean ridges. Such rocks can form only if molten material hardens quickly after erupting under water. The presence of these rocks supports the theory of sea-floor spreading. how to send money to palawanWebbSea floor spreading happens at places where plates are moving away from each other and where the liquid rock from the asthenosphere can come up to the lithosphere.
