What Is Sea Floor Spreading
Rifts are the site of geological activity including earthquakes.
What is sea floor spreading. Subduction and sea floor spreading are processes that could alter the size and form of the ocean. The mid atlantic ridge for instance separates the north american plate from the eurasian plate and the south american plate from the african plate. Sea floor spreading ocean floor spreading meeresbodenausweitung meeresbodenspreizung ausdehnung des meeresbodens infolge divergierender auseinander driftender ozeanischer platten plattentektonik. Seafloor spreading is a geologic process where there is a gradual addition o.
Seafloor spreading occurs along mid ocean ridgeslarge mountain ranges rising from the ocean floor. Seafloor spreading ist das langsame seitliche auseinanderweichen spreading des ozeanbodens seafloor an divergenten plattengrenzen als teilprozess der plattentektonik und damit der mantelkonvektion. The rate at which new oceanic lithosphere is added to each tectonic plate on either side of a mid ocean ridge is the spreading half rate and is equal to half of the spreading rate. For instance the atlantic ocean is believed to be expanding because of its few trenches.
Seafloor spreading is a process that occurs at mid ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Material from the asthenosphere becomes molten as convection. Sea floor spreading definition a process in which new ocean floor is created as molten material from the earths mantle rises in margins between plates or ridges and spreads out. Many of the worlds hydrothermal vents are found on or near the rifts that cause seafloor spreading.
Sea floor spreading is actually the creation of new oceanic basaltic crust at divergent plate boundaries called mid ocean ridges. Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. Due to this continuous seafloor spreading occurs and makes atlantic ocean floor to be connected to other continental crust making the ocean gets wider over the time.
