The ocean floor is expanding through a process of magnetic recording
In short: This video explains the mechanism of seafloor spreading, a cornerstone of plate tectonics. It explores how new crust is formed and how the Earth preserves a geological record of its own movement.
The core of the explanation focuses on four major pieces of evidence supporting seafloor spreading. A primary focus is the study of alternating magnetic bands preserved in rocks on both sides of mid-ocean ridges.
By examining these patterns, scientists can track how the seafloor moves away from central ridges, providing a clear visual and physical history of tectonic activity.
