Molten lava leaks out along the seams between tectonic plates in the earth's crust, at the sea bottom. Because the water is cold, the lava hardens quickly into rock, causing the sea floor to spread in both directions.
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 mechanism responsible for producing new seafloor between two diverging plates is seafloor spreading. Magma rises from the mantle to fill the gap created by the plates moving apart, solidifies upon contact with seawater, and forms new oceanic crust. This process results in the continuous growth of the ocean floor.
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.

Seafloor spreading is the process where new oceanic crust is formed at mid-ocean ridges and then moves apart, while continental drift refers to the movement of continents on the Earth's surface. Seafloor spreading is one mechanism that helps drive the movement of continents as part of plate tectonics.

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

Seafloor Spreading helped move the Continents to their current location.
Strengths of the seafloor spreading model include providing a mechanism for the movement of tectonic plates, explaining the age and magnetic patterns of the ocean floor, and supporting the theory of plate tectonics. Weaknesses include the lack of direct observation of seafloor spreading, the complexity of the processes involved, and the challenge of accurately dating oceanic crust.
In continental drift it says that they were drifted apart by the spin of the earth and in seafloor spreading the earths crust is drifted apart by the ridges in the mid-ocean.
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.
