What occurs at a divergent boundary?

At a divergent boundary, tectonic plates move apart from each other. This process occurs as magma rises from the mantle to fill the gap created when the plates separate, resulting in the formation of new oceanic crust. This can often lead to the creation of mid-ocean ridges, such as the Mid-Atlantic Ridge, where new material is continuously generated.

The movement apart of the plates allows for volcanic activity, which can manifest as underwater volcanoes or eruptions that create new landforms, particularly in oceanic settings. Essentially, divergent boundaries are significant in shaping the Earth's surface and contributing to the cycle of plate tectonics through the creation and renewal of crust.
