What geological process occurs at a divergent boundary?

At a divergent boundary, plates move away from each other, which is accurately described by the concept of plate divergence. This process leads to the formation of new crust as magma rises from below the Earth's surface to fill the gap created by the separating plates. This activity is often observed along mid-ocean ridges, where new oceanic crust is continuously formed as the tectonic plates pull apart. As the plates diverge, volcanic activity and the creation of rift valleys can also occur, highlighting the dynamic nature of geological processes at these boundaries.
