There is a mid ocean ridge that forms because the hot magma is lighter (less dense than the colder magma. The ridge is located at the spreading center. There are magnetic anomalies that can be thought of as stripes that mirror each other on either side of the spreading center. There are remnants of the pipes that form from upwelling hot springs (black smokers). There are pillow basalts that form from sudden cooling as it encounters sea water. It is generally rugged and rocky near the spreading center but tends to be more covered with sediments as you move away from it.
Seafloor spreading creates features such as mid-ocean ridges, ocean basins, and magnetic striping on the ocean floor. As tectonic plates move apart, magma rises to the surface, cools, and solidifies to create new seafloor. This process continuously generates new oceanic crust and reshapes the Earth's surface.

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 is triggered by a rift in a continental land mass.
Gravity in the oceanic crust is responsible for seafloor spreading.
Oceanic currents themselves do not directly cause seafloor spreading. Seafloor spreading is primarily driven by tectonic forces, specifically the movement of tectonic plates away from each other at mid-ocean ridges. This movement leads to the upwelling of magma from the mantle, creating new oceanic crust at the spreading center. Ocean currents can affect the distribution of heat and nutrients in the ocean, but they do not play a direct role in the process of seafloor spreading.

Seafloor Spreading helped move the Continents to their current location.
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
symmetrical spreading of the ocean floor at mid-ocean ridges, where molten material rises to create new seafloor. As this material cools and solidifies, it records the Earth's magnetic field at the time, creating magnetic stripes on the seafloor. This phenomenon provides evidence for seafloor spreading and plate tectonics.
