Is sea floor spreading divergent
WitrynaAs 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 … WitrynaSea Floor Spreading theory. The process of seafloor spreading happens at mid-ocean ridges, where new oceanic crust is generated by volcanic activity and then progressively travels away from the ridge. Harry Hess suggested the theory that the seafloor moves (and carries the continents with it) as it expands from a central axis.

In 1967, McKenzie and Parker suggested the theory of plate tectonics. Morgan later outlined the theory in 1968. According to the theory of plate tectonics, the earth’s lithosphere is …
Witrynaanswer choices. The two plates would push apart and form a rift zone. The oceanic plate would rise up over the continental plate. The oceanic plate would sink under the continental plate. The two plates would meet head on and rise up to form mountains. Question 5. 60 seconds. 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). The age-depth relation can be modeled by the cooling of a lithosphere plate or mantle half-space in areas without significant subduction. In the mantle half-space model, the seabed height is determined by the oceanic lithosphere and …
WitrynaSea-Floor Spreading Answer Key. This is a mid-ocean ridge. It is an underwater mountain range that forms when magma pushes up on the crust at a divergent boundary. Seafloor spreading is happening at B. Molten rock pushes up from the asthenosphere and pushes the plates apart at the mid-ocean ridge. This creates new …
