NettetSeafloor spreading is the process that occurs at mid- ocean ridges, where ocean crust is formed throughvolcanic activity and then gradually moves away from the ridgesA. TRUE B. FALSE5. Seafloor spreading is consistent at all mid- ocean ridges?A. TRUE B. FALSE 15. New rock is created at ocean ridges, pushing the older ocean floor from the ridges. Nettet19. nov. 2024 · The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way …

Originally the Continental Drift Hypothesis was not well received by other scientists. Why. Striations. Which of these means scratches in rocks caused by glaciers. Nettet28. if magnetic reversals are recorded in the seafloor what kind of rock is the seafloor made. VOLCANIC ROCK. The seafloor is made of volcanic rock that solidified from …
Nettet27. sep. 2024 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and … NettetThe age of the sea-floor also supports sea-floor spreading. If sea-floor spreading operates, the youngest oceanic crust should be found at the ridges and progressively …
NettetNamely, seafloor spreading explained that tectonic plates—including continents—move because of convection in Earth’s interior. Thus, instead of needing to move through oceanic crust, as Wegener’s model had suggested, Hess’s model had continents moving with seafloor—as it is created and recycled.
NettetWhat is seafloor spreading? Why is it less likely to occur in the Pacific ocean basin than in the Atlantic ocean basin? Explain how you think seafloor spreading and subduction recycle Earth’s materials. Explain the formation process of a mid-ocean island from a hot spot to an atoll. What are the major processes that cause these changes? thief iiNettet2. jan. 2024 · Seafloor Spreading Theory was put forth by American geophysicist Harry H. Hess in 1960. Magma rising in the rift as the old crust pulls itself in opposing directions causes the seafloor to spread. The seawater cools the lava, creating a fresh crust. Over millions of years, the magma’s upward flow and subsequent cooling produced high … thief iiiNettet31. mai 2024 · What is the first step of seafloor spreading? 1. A long crack in the oceanic crust forms at a mid ocean ridge. 2. Molten material rises and erupts along the ridge. … sail trainyards ottawa hoursNettet24. sep. 2024 · Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle’s convection currents … sail trilogy couponNettetSea floor spreading occurs at the mid-ocean ridge where two plates are moving away from each other.
