What is the main feature of a divergent boundary?

The main feature of a divergent boundary is that plates are moving away from each other. This separation occurs in locations where tectonic plates are spreading apart, such as at mid-ocean ridges. As the plates drift apart, magma rises from beneath the Earth's crust to fill the gap, creating new oceanic crust. This process is responsible for the formation of new geological features, like ocean ridges and rift valleys. Divergent boundaries are often associated with volcanic activity and the generation of new seafloor, playing a crucial role in the plate tectonics theory by contributing to the overall movement of Earth's lithosphere.
