sea-floor spreading is caused by deep-ocean trenches that overflows and makes a new layer come out. heres a video if you would like to watch it.science.discovery.com/videos/...shorts-sea-floor-spreading.html
They proved that the seafloor was spreading.
A diagram that shows how seafloor spreading works.
Gravity in the oceanic crust is responsible for seafloor spreading.
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.
Seafloor Spreading helped move the Continents to their current location.

They proved that the seafloor was spreading.
The primary force driving seafloor spreading and continental drift is mantle convection. Heat from Earth's core causes the mantle to circulate, creating convection currents that move tectonic plates, leading to the spreading of the seafloor and movement of continents.

Seafloor spreading is triggered by a rift in a continental land mass.

Seafloor Spreading helped move the Continents to their current location.
Most convection currents that cause seafloor spreading are thought to be located in the asthenosphere, which is a semi-fluid layer of the Earth's upper mantle beneath the lithosphere. The movement of these convection currents is believed to drive the motion of tectonic plates.
