Where Does New Seafloor Form. When oceanic plates diverge, tensional stress causes fractures to occur in the. Sometimes lava erupts and flows from long cracks in the earths crust called fissures.

As tectonic plates move away from each other, magma rises from. Lava flows from fissures on the. Web very little of the sea floor is older than 150 million years. Web new seafloor forms at locations where tectonic plates are moving apart, allowing magma to rise and solidify as it cools. Sometimes lava erupts and flows from long cracks in the earths crust called fissures. As new seafloor moves away. As new seafloor forms at the ridges and is pushed away on either side, the crust on both sides gets slowly colder and older. The seafloor is formed as the earth’s lithosphere and mantle interact and interact with the sea. As a result, the ocean floors move like conveyor. As the seafloor spread apart at magma is forced upward and flows from new seafloor.
Seafloor spreading helps explain continental drift in the theory of plate tectonics. Web new seafloor forms at locations where tectonic plates are moving apart, allowing magma to rise and solidify as it cools. Seafloor spreading helps explain continental drift in the theory of plate tectonics. Web the process that continually adds new seafloor to the ocean. Lava flows from fissures on the. As tectonic plates move away from each other, magma rises from. Where does new material during the process of sea floor spreading come from? What form along mid ocean ridges? As a result, the ocean floors move like conveyor. Sometimes lava erupts and flows from long cracks in the earths crust called fissures. The seafloor is formed as the earth’s lithosphere and mantle interact and interact with the sea.
