Estimates of hydrate saturation and distribution rely on drilling expeditions and seismic surveys that tend to provide either large-scale estimates or highly localized well data. In this study, hydrate …
WebWhen the concept of seafloor spreading came along, scientists recognized that it was the mechanism to explain how continents could move around Earth’s surface. Scientific data and observation now allows us to merge the ideas of continental drift and seafloor spreading into the theory of plate tectonics. WebDetermination of plate thickness After marine magnetic anomalies were explained, the cumulative evidence caused the concept of seafloor spreading to be widely accepted. However, the process responsible for continental drift remained enigmatic. Two important concerns remained.
WebSeafloor Spreading at Mid-Ocean Ridges Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21). WebMar 21, 2024 · The concept of seafloor spreading forms an integral part of the modern plate tectonics theory and helps to explain continental drift. The movement of oceanic plates at divergent boundaries leads to the development of fractures in the lithosphere due to tensional stress.
WebSeafloor 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 …
WebApr 9, 2024 · New oceanic crust forms at these ridges through seafloor spreading, which pushes the plates apart.
