The Super Continent was broken apart, in part by sea-floor spreading.Scientists discovered that sea-floor spreading continues to move the continents.Sea-floor spreading can be measured using specialized equipment.
There are three processes that add material to the ocean floor: Sedimentation, and Vulcanism. Sedimentation is usually caused by skeletons of sea animals falling to the ocean floor. It can be argued that this is not new material but only recycled materials. But some of the remains are calcium or other deposits that are added from land based run off. Silt deposits also run into the ocean floor from the land, Vulcanism results from shifts in the ocean mantle with new material coming from deeper in the earth and spouting through volcanoes or emerging as new ocean floor at the rising edges of the tectonic plates.
The movement of moltenmaterial in the mantle creates conveyor belts of magma is because of sea-floor spreading. Its part of the process.
No, Alfred Wegener did not use sea-floor spreading, ridge push, or slab pull to develop his hypothesis of continental drift. Wegener proposed his theory in 1912, long before these concepts were formulated in the mid-20th century as part of the theory of plate tectonics. Instead, Wegener based his hypothesis on evidence such as the fit of continental coastlines, fossil distribution, and geological similarities across continents. The mechanisms of sea-floor spreading and plate tectonics were developed later to explain the movement of continents.
When magma rises through sea floor rifts, it cools and solidifies into new oceanic crust as part of the process known as seafloor spreading. This creates new crust at the boundaries of tectonic plates, contributing to the continual movement and renewal of the Earth's outer shell.

Sea floor spreading is part of the geologic activity know as plate tectonics.
in a way, they are both part of the process called sea floor spreading. the trench is where the ocean floor is subducted and the rift valley is where the molten material comes up and cools.
The first process is called sea-floor spreading (rifting when it happens on land) and the second process is called subduction. Both processes are part of plate tectonics.
The thinnest part of a tectonic plate is typically at its edges, where the plate may be undergoing subduction or seafloor spreading. These processes can cause the plate to be thinner due to intense geological activity.
