Divergent plate boundaries are fascinating geological features where tectonic plates move apart, leading to the creation of new crust. This process is driven by mantle convection and can result in the formation of mid-ocean ridges and rift valleys. The study of these boundaries, including the role of hotspots and magnetic anomalies, is essential for understanding plate tectonics and the Earth's evolving landscape. Notable examples include the Mid-Atlantic Ridge and the East African Rift.

Divergent plate boundaries are areas where two tectonic plates are moving apart from each other
Mechanisms behind formation
Divergent boundaries are formed by mantle convection, which drives the plates apart and creates new crust through the ascension of magma
Influence of hotspots
Hotspots can initiate the formation of divergent boundaries by fracturing the lithosphere and creating new plate boundaries
Divergent boundaries exhibit different characteristics in oceanic and continental settings, with oceanic boundaries creating mid-ocean ridges and continental boundaries forming rift valleys
Divergent boundaries can be found around the world, with notable examples including the Mid-Atlantic Ridge, the Red Sea Rift, and the East African Rift
