Seafloor spreading rate
Jul 13, 2015 Sea Floor Spreading early 1960's- Harry Hess, together with Robert Dietz Calculate the rate of seafloor spreading using magnetic clues. We use these additional pieces of information to detect changes in spreading rate, ridge length, and sea- floor production rates as functions of time and between Spreading rate is the rate at which an ocean basin widens due to seafloor spreading. (The rate at which new oceanic lithosphere is added to each tectonic plate a total spreading rate of 2.5–7.5 mm/yr. Gracia et al. (1996) gave a maximum age of seafloor spreading of 0.7 Ma and a rate of 0.83 mm/yr total spreading rate. Seafloor spreading is the process where new oceanic crust is formed at the Rates of subduction are typically measured in centimeters per year, with the describing the mid-ocean ridge system and deep-ocean trenches. • Determine the rate of sea-floor spreading that occurs along a mid-ocean ridge by using. In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.
This rate is mms/yr or less and will decrease as a square root function with distance from the ridge that crust formed at. For the transform component the strike-slip
The typical rates of seafloor spreading is 5 centimeters per year. Seafloor spreading is a process that occurs at mid ocean ridges. Seafloor spreading occurs along mid-ocean ridges—large mountain ranges rising from the ocean floor. The Mid-Atlantic Ridge, for instance, separates the North American plate from the Eurasian plate, and the South American plate from the African plate. The East Pacific Rise is a mid-ocean ridge that runs through the eastern Pacific Ocean and separates the Pacific plate from the North American plate, the Cocos plate, the Nazca plate, and the Antarctic plate. Let's determine the average rate of seafloor spreading since the lithosphere at point A was formed (you will do this again in the next expedition). Let's also assume for this problem that seafloor spreading is symmetric, i.e. the rate of plate formation is the same on the left side for Plate NA as it is for the right side for Plate EU. At the spreading center on a mid-ocean ridge the depth of the seafloor is approximately 2,600 meters (8,500 ft). On the ridge flanks the depth of the seafloor (or the height of a location on a mid-ocean ridge above a base-level) is closely correlated with its age (age of the lithosphere where depth is measured). Seafloor spreading, theory that oceanic crust forms along submarine mountain zones, known collectively as the mid-ocean ridge system, and spreads out laterally away from them. This idea played a pivotal role in the development of plate tectonics, a theory that revolutionized geologic thought during The age, spreading rate, and asymmetry at each grid node are determined by linear interpolation between adjacent seafloor isochrons in the direction of spreading. Ages for ocean floor between the oldest identified magnetic anomalies and continental crust are interpolated by geological estimates of the ages of passive continental margin segments. When seafloor spreading occurs, it pushes the underground magma up though the new crust, creating a sort of volcano out of the new crust. Magma is a very important part in seafloor spreading.

Seafloor spreading, theory that oceanic crust forms along submarine mountain are believed to be moving away from the Mid-Atlantic Ridge at a rate of 1–2 cm Consequently, the spreading rate on one side of a ridge is often referred to as the “half rate”. Values are usually quoted in km Myr−1 (mm yr−1).
