Shifting of Tectonic plates away from each other.
New crust is formed at mid-ocean ridges through a process called seafloor spreading. Magma rises to the surface, cools, and solidifies, creating new oceanic crust. This process continually adds new material to the ocean floor, expanding the Earth's crust.
The mechanism responsible for producing new oceanic crust between two diverging plates is seafloor spreading. Magma rises up from the mantle at mid-ocean ridges, solidifies upon reaching the seafloor, and forms new crust. As the plates move apart, this process continuously adds new material to the ocean floor.
The process that forms new seafloor is called seafloor spreading. It occurs at mid-ocean ridges where new oceanic crust is created through volcanic activity. As magma rises and solidifies, it adds to the seafloor, pushing older crust away from the ridge and creating a continuous process of crust formation.
The movement of earth's crustal plates causes divergent boundaries where plates move apart, allowing magma to rise from below and solidify to form new crust. This process creates mid-ocean ridges, which is where new oceanic crust is formed. Over time, as more crust is added, the ocean basin widens and gets deeper.
The major source of oceanic salinity is the dissolution of ions from rocks on land that are carried into the ocean by rivers. This process adds various salts to seawater, contributing to its overall salinity. Additionally, hydrothermal vents on the ocean floor can also introduce elements and minerals that affect salinity.
sea floor spreading
Volcanic eruptions are one process that adds new material to crust. Lava from the volcanoes eventually cool, forming new land. Sea floor spreading also adds new material to the crust.

sea floor spreading
the formation of new oceanic crust. Magma rises to the surface at mid-ocean ridges, solidifies upon contact with seawater, and creates new crust as it spreads horizontally away from the ridge axis. This process continually adds new crust to the ocean floor as tectonic plates move apart.
