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.
Molten rock at mid-ocean ridges is the result of sea-floor spreading. WRONG
The movement of moltenmaterial in the mantle creates conveyor belts of magma is because of sea-floor spreading. Its part of the process.
When seafloor spreading occurs, it pushes the underground magma up though the new crust, creating a sort of volcano out of the new crust. Magma is a very important part in seafloor spreading. :]

Sea floor spreading is part of the geologic activity know as plate tectonics.
Lots of water will evaporate very fast and the mantle's compositions would harden and solidify to become part of a new sea floor. This is what scientists call 'sea-floor spreading'.
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.

Because of erosion, or because of sea floor spreading. Sea floor spreading would be the cause of it because it moves the rock to a submerging area and the mantle's hot "body" melts it. Now erosion would be part of it because it erodes the rock away, leaving sand or dirt from that rock. If they were looking for ancient sand, then they would most definitely find it.

They both the brothers played a big part in spreading the word of god, by miracles and wonders and signs.
