sea-floor spreading
The process is called seafloor spreading. It occurs at mid-ocean ridges where tectonic plates move apart, allowing magma to rise from the mantle and cool and solidify, creating new oceanic crust. This process is driven by plate tectonics and results in the continuous expansion of the ocean basins.
Seafloor spreading is the geologic process that forms new crust on the ocean floor. This occurs at mid-ocean ridges, where tectonic plates move apart and magma rises to the surface, solidifying to form new oceanic crust.
A mid-ocean ridge forms as tectonic plates move apart, creating a gap where magma rises from the mantle to form new crust. This process is known as seafloor spreading and results in the continuous growth of the ocean floor.
Extrusive igneous rock- Sometimes lava erupts and flows from long cracks in the earths crust called fissures. Lava flows from fissures on the ocean floor at places where tension is causing the ocean to be pulled apart. This lava cools to form new ocean floor. Hope it helps.
Sea floor spreading is the process that creates new oceanic crust at mid-ocean ridges, which are underwater mountain ranges. As the new crust forms, it moves away from the ridge, pushing the existing ocean floor aside. This movement is what allows continents to drift apart from each other, as the forces generated by sea floor spreading contribute to the overall movement of tectonic plates.

Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.

Seafloor spreading is the geologic process that forms new crust on the ocean floor. This occurs at mid-ocean ridges, where tectonic plates move apart and magma rises to the surface, solidifying to form new oceanic crust.
New crust forms on the ocean floor through seafloor spreading, where magma rises up from the mantle through mid-ocean ridges and solidifies into new crust as tectonic plates move apart.
It causes what we call "sea-floor spreading." Sea-floor spreading is the process in which the ocean floor is extended when two plates move apart. As the plates move apart, the rocks break and form a crack between the plates. Earthquakes occur along the plate boundary. Magma rises through the cracks and seeps out onto the ocean floor like a long, thin, undersea volcano.
