* Seafloor Spreading: This is the process where new oceanic crust is formed at mid-ocean ridges.
* Mid-Ocean Ridges: These are underwater mountain ranges where magma (molten rock) rises from the Earth's mantle.
* Magma Rises: As the tectonic plates move apart, magma rises from the mantle, cools, and solidifies, creating new oceanic crust.
* Crust Moves Apart: This new crust is pushed away from the ridge as more magma rises, continuing the process of seafloor spreading.
In short: Seafloor spreading is the process by which new oceanic crust is created at mid-ocean ridges as the tectonic plates move apart.
