Yes tho, my book says something like that I how I see here, yes.
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.
Mid-Ocean ridges.
Seafloor spreading occurs at the boundary between two tectonic plates. As the plates divide, magma comes up through the crack and cools to form new sea floor. The farther away the floor is from the boundary, the older it is.
2. Mid Ocean Ridges are the place where new crust is formed. 1. oceanic plates or oceanic crust
When seafloor spreading occurs at the boundary between tectonic plates, it typically takes place at mid-ocean ridges, where two oceanic plates diverge. As the plates pull apart, magma rises from the mantle to fill the gap, solidifying to form new oceanic crust. This process not only creates new seafloor but also contributes to the age progression of the ocean floor, with younger rocks located closer to the ridge and older rocks further away. Seafloor spreading is a key mechanism of plate tectonics and plays a significant role in shaping ocean basins.
Mid-oceanic ridges
The Mid-Atlantic-Ridge is where two of Earth's plates split apart. The Mid-Atlantic-Ridge was formed along a divergent boundary where seafloor spreading is taking place.
One weakness of the seafloor spreading theory is the question of what drives the movement of the tectonic plates apart in the first place. The mechanism behind this driving force is still not fully understood. Additionally, there are discrepancies in the rate of spreading and the age of the oceanic crust in certain regions, leading to some uncertainties in the theory.
You can find the seafloor spreading in the middle of the Atlantic Ocean. It is pushing Europe and Africa away from North and South America. You can go to Iceland and stand on the place where the spreading seafloor comes onto land. There, you can put one foot on Europe and one foot on America. It would be quite a while before your feet became another inch apart.
One example would be...the mid-atlantic ridge.
