How is new rock added to the ocean floor?
New rock is added to the ocean floor through a process called seafloor spreading, where magma rises from the Earth's mantle at mid-ocean ridges, cools and solidifies to form new oceanic crust. This process helps expand the ocean floor and contributes to the movement of tectonic plates.
What is it called when two oceanic plates move apart and new crust is formed?
This process is called seafloor spreading. As the two plates move apart, magma rises from the mantle to create new crust at the mid-ocean ridge. This process helps explain the movement of Earth's tectonic plates and the reshaping of the ocean floor.
What is the process that continually adds new material to the ocean floor is called?
sea-floor spreading
Who discovered Seafloor Spreading?

In the process of sea floor spreading what happens when magma rises to the earths surface and solidifies?
Yes. Seafloor spreading is the term given to the creation of new seafloor at divergent boundaries. At a divergent boundary, two oceanic plates move apart, which obviously means that something must then surface to fill the void. This is where the magma rises from the Earth's interior and cools to become seafloor. On the other end, at convergent boundaries, the old seafloor is forced under the continental plates, where it is recycled back into the Earth's magma supply.

How do the ages of the rocks on the ocean floor support the theory of seafloor spreading?
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.

What evidence in rock supports the theory of seafloor spreading?
Convergence supports the theory of seafloor spreading. Samples of the deep ocean floor are evidence of seafloor spreading because the basaltic oceanic crust and overlapping sediment become younger as the mid-ocean ridge is approached. Also, the rock that makes up the floor of the ocean is younger than the continents.

What process in which new sea floor forms as older sea floor is pulled apart?
Seafloor spreading where new floor is formed. Subduction zone where older floor is pushed back into the mantle.
What is ocean-floor spreading?
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge. Seafloor spreading helps explain continental drift in the theory of plate tectonics.
How does magma help seafloor spreading?
Magma plays a crucial role in seafloor spreading as it rises from the mantle at mid-ocean ridges, where tectonic plates are diverging. When magma reaches the ocean floor, it cools and solidifies, forming new oceanic crust. This process not only creates new seafloor but also pushes older crust away from the ridge, facilitating the movement of tectonic plates. As a result, seafloor spreading continuously reshapes the ocean floor and contributes to geological activity.
What is seafloor spreading and what forms as a result of seafloor spreading?
Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates diverge and magma rises to the surface. This results in the creation of new ocean floor, leading to the expansion of ocean basins. As seafloor spreading occurs, features such as mid-ocean ridges, rift valleys, and volcanic islands can also form as a consequence. Additionally, this process contributes to the cycle of plate tectonics, influencing geological activity and the distribution of continents.
How does the ocean floor move?
It is called Seafloor Spreading, which comes under the Divergent Plate Movement.
