Seafloor spreading shows that tectonic plates move away from each other.

Answer 1

Seafloor spreading at mid-ocean ridges provides evidence of continental drift because it demonstrates that tectonic plates are moving away from each other, causing new oceanic crust to form and pushing apart the continents on either side of the ridge. This supports the theory that the continents were once joined in a single landmass (Pangaea) and have slowly drifted apart over millions of years.
