Answer:
The formation of new crust on the ocean floor occurs through a process known as seafloor spreading. This process takes place at mid-ocean ridges, where tectonic plates are moving apart. Magma rises from the mantle to fill the gap, cools, and solidifies, forming new oceanic crust. As the plates continue to separate, the newly formed crust is pushed away from the ridge, creating new seafloor and contributing to the ongoing dynamic of plate tectonics.
