Where Does New Seafloor Form. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Lava flows from fissures on the.

This process is known as seafloor spreading. Sometimes lava erupts and flows from long cracks in the earths crust called fissures. Seafloor spreading helps explain continental drift in the theory of plate tectonics. 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 new seafloor forms at the ridges and is pushed away on either side, the crust on both sides gets slowly colder and older. Web very little of the sea floor is older than 150 million years. Web the youngest sea floor is found near ocean ridges where magma is coming up and then cooling to form new crust. As new seafloor moves away. Web why are these the flattest plains on the planet?
When oceanic plates diverge, tensional stress causes fractures to occur in the. Web the youngest sea floor is found near ocean ridges where magma is coming up and then cooling to form new crust. As new seafloor moves away. Molten material that erupts then. Seafloor spreading helps explain continental drift in the theory of plate tectonics. As new seafloor forms at the ridges and is pushed away on either side, the crust on both sides gets slowly colder and older. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Web why are these the flattest plains on the planet? The seafloor is formed as the earth’s lithosphere and mantle interact and interact with the sea. 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.
