Webb21 dec. 2024 · Seafloor spreading is the continuous process of forming new igneous rock at midocean ridges by injection of magma that forms new seafloor. The process is continuous because forces cause opposite sides of the midocean ridge to constantly move apart, making new room for the process to repeat. Webb8 okt. 2024 · When Earth’s tectonic plates grind past one another, enormous amounts of energy can be released in the form of earthquakes. Is sea floor spreading being beneficial or harmful to Earth? Answer : Mid-ocean ridges …
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 … Webb16 apr. 2024 · A new global analysis of the last 19 million years of seafloor spreading rates found they have been slowing down. Geologists want to know why the seafloor is getting sluggish. New oceanic crust forms continuously along rifts thousands of miles long on the seafloor, driven by plate tectonics. As subduction pulls old crust down, rifts open up ...
