Nettet20. nov. 2024 · As a fast-spreading center, the East Pacific Rise creates new seafloor at a rate of 6 to 16 centimeters, or 3-6 inches, each year. Because of this rapid rate of seafloor spreading, a trench has ... NettetLobate flows resemble on-land pahoehoe flows, but are a bit more inflated-looking.They are very common on fast-spreading mid-ocean ridges such as the East PacificRise. Sheet flows form at much higher eruption rates than pillow flows. The high eruptionrates allow rivers of lavas to form that can flow across the seafloor.

NettetA theoretical model of the formation of magnetic striping. New oceanic crust forming continuously at the crest of the mid-ocean ridge cools and becomes increasingly older as it moves away from the ridge crest with seafloor spreading (see text): a. the spreading ridge about 5 million years ago; b. about 2 to 3 million years ago; and c. present-day. NettetSeafloor Spreading at Mid-Ocean Ridges. Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig. 7.21). frye boots black
