The seafloor spreading is a process that occurs at the divergent plate boundaries. What this process does is basically pilling up new crust at the divergent boundary, created from the magma that cools off, and pushes the old crust further away from it. As the old crust is pushed away, it results in movements of the continental plates. As they are moving, eventually they come to a situation to collide with one another. As they collide, they practically merge, creating one larger continental mass from the previously existent two, as that continues, more and more continental plates will merge, with the end result being a single enormous continental mass, a supercontinent composed of all the previously existent continental masses.
Answer:
The seafloor spreading is the splitting of the ocean that results due to the plate tectonic movement. These plates are constantly moving over the last millions of years that can lead to the joining of all the landmasses forming a super continent.
Explanation:
Seafloor spreading refers to the divergent motion of the oceanic plates that occurs due to the plate tectonic movement. The earth initially was comprised of a single landmass named Pangea, in association with a large body of water. This super continent got split up due to this plate motion and configured the present scenario. It is also believed that after about 250 million years, all the landmasses will again combine together to form a super continent, due to this continuous plate motion.
The Plate tectonic theory describes the movement of the lithospheric plates over a less dense layer of Asthenosphere due to the generation of convection current in the mantle, and this is formed because of the heat radiated from the core of the earth.
Further explanation:
The Seafloor spreading concept was introduced by Harry Hess and helped in understanding the reason behind the plate motion (continental drift). This is defined as the separation of oceanic crust because of the formation of mantle convection.
A couple of evidence was forwarded in support of the Continental drift theory. Some of it includes the presence of similar fossil plants and animals in separate continents, the edges of the continents perfectly fit one another, correlation of rocks, and so on.
This theory is an association with the Plate tectonic theory depicts that the earth initially was comprised of a single landmass which was known as the Pangea.
It also enabled the geophysicists to determine the interior of the earth, the composition of the different layers, and the difference in their densities. The earth's core contains a large number of molten materials that radiate a significant amount of energy as a result of which the lithospheric plates move.
This drifting of the continents was a major discovery in the world of geology. This helped the geologists and geophysicists in evaluating and picturing how the various geological processes have been taking place on the surface of the earth since the geological time.
