Nettet9. apr. 2024 · There is currently evidence that Africa is splitting into two continents, allowing space for a new ocean to come rushing in. This proof came in the form of volcanic eruptions in 2005, which initiated the theory of Africa's split, and cracks forming in Kenya in 2024 confirmed the suspicion. The African continent, located on the African Plate, is ... 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. NettetWhere does seafloor spreading occur? Oceanic Plates: The surface of our world is called the crust, and that crust is divided up into separate plates.

NettetSea floor spreading occurs at the mid-ocean ridge where two plates are moving away from each other. Here, magma rises up from below as the sea floor spreads out to … Nettet25. apr. 2024 · Seafloor spreading is the process of magma welling up in the rift as the old crust pulls itself in opposite directions. Cold seawater cools the magma, creating a new crust. The upward movement and eventual cooling of this magma has created high ridges on the ocean floor over millions of years.

NettetWhat is the process of sea-floor spreading? In sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them. What is the evidence for sea-floor spreading?

NettetWhat is seafloor spreading? Why is it less likely to occur in the Pacific ocean basin than in the Atlantic ocean basin?
