    Sea-floor spreading provides a way for continents to move, because when sea-floor spreading occurs, new oceanic lithosphere forms. Also, when tectonic plates move apart, the sea-floor spreads apart and magma fills the gap.

    scientists found the mid ocean ridge which is in the middle of most of the oceans and lava comes out of it and this shows that there must be moving plates because they are moving apart and letting lava come out. hope i helped. you can look up sea floor spreading if you need more information.
