How to Build a Model Illustrating Sea-Floor Spreading and Subduction ... Based on the pattern and spacing of the oceanic magnetic stripes and the inferred motion of the plates, the age of the ocean floor can be determined.

Dietz and Hess were among the small handful who really understood the broad implications of sea floor spreading. If the Earth's crust was expanding along the oceanic ridges, Hess reasoned, it must be shrinking elsewhere. ... According to Hess, the Atlantic Ocean was expanding while the Pacific Ocean was shrinking.

Seafloor spreading occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental d...

Sea floor spreading is one component of the theory of plate tectonics. According to this concept, at ridges in many of the world's oceans (mid-ocean ridges), new crustal rock is added to the edges ... Using the age of the rock you have chosen and its distance from the MAR, calculate the half-rate of sea floor spreading,

DESCRIPTION: "Ring of Fire", Plate Tectonics, Sea-Floor Spreading, Subduction Zones, "Hot Spots" ... According to the new, generally accepted "plate-tectonics" theory, scientists believe that the Earth's surface is broken into a number of shifting slabs or plates, which average about 50 miles in thickness.

According to Wegner, about 200 million years ago, all the continents had been joined in a single ... Stripes of approximately the same size should be carried away from either side of the ridge as spreading pulls the new oceanic crust apart. Sea-floor spreading is also supported by the age of the seafloor.

Brightness contrasts mark a discontinuity in plate age and thus in plate thickness. The brightness contrast on one side of ... We have shown that a wax model of sea-floor spreading, under the right conditions, produces tectonic microplates that evolve in time according to a kinematic model designed for oceanic microplates.

Thus, serpentinization and unroofing were time-transgressive and the age of the non-volcanic sea floor formed by the unroofed mantle grows younger outboard, just as is the case for normal, volcanic sea floor.
