Divergent boundaries are areas where two tectonic plates move away from each other. This movement creates new crust as magma rises from the mantle to fill the gap. These boundaries are often found along mid-ocean ridges, such as the Mid-Atlantic Ridge, where the ocean floor is formed. As the plates separate, earthquakes can occur, and volcanic activity may be present. The formation of new land can also lead to the creation of features like rift valleys. Overall, divergent boundaries play a crucial role in the Earth's geological processes and the recycling of crustal material.
