Explanation:
Detailed explanation-1: -Seafloor spreading is a geologic process in which tectonic plates-large slabs of Earth’s lithosphere-split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection.
Detailed explanation-2: -Seafloor-spreading rates are much more rapid in the Pacific Ocean than in the Atlantic and Indian oceans. At spreading rates of about 15 cm (6 inches) per year, the entire crust beneath the Pacific Ocean (about 15, 000 km [9, 300 miles] wide) could be produced in 100 million years.
Detailed explanation-3: -Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.
