Web very little of the sea floor is older than 150 million years. As the seafloor spread apart at magma is forced upward and flows from new seafloor. What form along mid ocean ridges? Seafloor spreading helps explain continental drift in the theory of plate tectonics. As tectonic plates move away from each other, magma rises from. The seafloor is formed as the earth’s lithosphere and mantle interact and interact with the sea. When oceanic plates diverge, tensional stress causes fractures to occur in the. Molten material that erupts then. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Sometimes lava erupts and flows from long cracks in the earths crust called fissures.
This process is known as seafloor spreading. Seafloor spreading helps explain continental drift in the theory of plate tectonics. Lava flows from fissures on the. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Where does new material during the process of sea floor spreading come from? Web very little of the sea floor is older than 150 million years. This process is known as seafloor spreading. When oceanic plates diverge, tensional stress causes fractures to occur in the. Web new seafloor forms at locations where tectonic plates are moving apart, allowing magma to rise and solidify as it cools. Web the process that continually adds new seafloor to the ocean. Web the youngest sea floor is found near ocean ridges where magma is coming up and then cooling to form new crust.
