WebHow can the ocean floor be created and/or destroyed? New crust is created due to seafloor spreading. When the plates spread magma is forced through the cracks and cools forming new land. At subduction zones where plates meet some crust can be forced underneath other crust causing the destruction of ocean floor. fitfeelsgood.com/bookWebAs upwelling of magma continues, the plates continue to diverge, a process known as seafloor spreading. Samples collected from the ocean floor show that the age of oceanic crust increases with distance from the spreading centre—important evidence in favour of this process. These age data also allow the rate of seafloor spreading to be determined, and … can heat affect blood pressureWeb1 de abr. de 2010 · Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. The tectonic plates are constantly in motion and new surfaces are always being created. This continual motion is evidenced by the occurrence of earthquakes and volcanoes. fit feels good reviewsWeb23 de nov. de 2010 · Study now. See answer (1) Best Answer. Copy. Extrusive igneous rock-.
