seafloor spreading affects us with help from continental drift. seafloor spreading creates new seafloors, but moves the continents a few centimeters apart from each other every year. in many years, pangaea will become aeagnap, because the continents will become one big land again, but backwards, and will damage the faults and the only land we have severely.
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.
Typical rates of spreading average around 5 centimeter (2 inches) per year.
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.
Magnetism is used to support the theory of seafloor spreading through the study of magnetic stripes on the seafloor. These stripes are aligned with the Earth's magnetic field and provide evidence for the process of seafloor spreading, where new oceanic crust is formed at mid-ocean ridges. As the crust cools and solidifies, the magnetic minerals in the rocks align with the Earth's magnetic field, creating a record of magnetic reversals over time that support the theory of seafloor spreading.
seafloor spreading
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.
Seafloor spreading is triggered by a rift in a continental land mass.
The observation of the alternating magnetic stripes on the seafloor was instrumental in formulating the hypothesis of seafloor spreading.
Seafloor Spreading helped move the Continents to their current location.

Seafloor Spreading
how am i suposed to know
No, seafloor spreading does not hold the plates in place. Seafloor spreading is a process that occurs at mid-ocean ridges where new oceanic crust is formed and spreads apart. It is driven by the movement of tectonic plates, which are actually responsible for holding the seafloor in place.
It helped us by creating the theory of seafloor spreading which is the proof alfred needed to complete his hypothesis
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. :]
