Can you please compare sea-floor spreading with the formation of mid-ocean ridges?!
yes mid-ocean ridges an sea-floor spreading are linked. the mid-ocean ridge is an area that is mountainess and the spreading is slower in the Atlantic.But in the Pacific the mid- ocean ridge is much smooth it more like hills. the spading of the ocean ridges are caused by the plate boundaries moving apart form each other in different directions
Sea Floor Spreading Information
When there is hot magma rising from the mantle to the ocean floor, the heat and pressure creates a weakness in the oceanic crust, cracks it, splits it apart, and thus, you have sea-floor spreading. The more magma rising from the mantle, the more the sea-floor spreads. Each time the sea-floor spreads and cools, it forms a ridge on both sides of the crack. If you have multiple events of magma rising, sea-floor spreading, magma cooling to form ridges, then eventually, you form mid-ocean ridges. For example, imagining pushing a rug against a door or wall, the rug crumbles. If you cut the rug in half and push each part of the rug in the opposite direction towards a wall, you're making making a real life mid-house ridge! =)
