Is seafloor spreading because new material is being added is the atmosphere
1 answer
No, sea floor spreading is not caused by new material being added to the atmosphere. Seafloor spreading is the process by which new oceanic crust is formed through the upwelling of molten material from the Earth's mantle at mid-ocean ridges. As the new material rises and spreads out, it pushes apart the existing crust on either side, creating a gap where new crust is continuously formed. This process plays a key role in plate tectonics and the movement of Earth's continents. The atmosphere, on the other hand, is a layer of gases surrounding the Earth and has no direct role in sea floor spreading.
