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.
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. :]
Magnetic stripes on the seafloor showed alternating patterns of normal and reversed polarity, matching Earth's magnetic field reversals. Age dating of seafloor rocks revealed that rocks were youngest along mid-ocean ridges and oldest near continental margins. Sediment thickness on the seafloor was thinnest at mid-ocean ridges and thickest near the continents, supporting the idea of seafloor 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.
