What is divergent tectonic plate movement?

Divergent tectonic plate movement occurs when two tectonic plates move away from each other. This process is primarily seen at mid-ocean ridges, where volcanic activity creates new oceanic crust as magma rises from the mantle. As the plates separate, magma fills the gap, leading to the formation of new oceanic features and contributing to seafloor spreading. This movement can also create rift valleys on land, where the Earth’s crust is being pulled apart.

This type of tectonic activity plays a crucial role in the geological cycle, influencing the Earth's surface, shaping continents and oceans, and affecting seismic activity. Understanding divergent boundaries helps in grasping the dynamics of plate tectonics, which is essential for comprehending various geological phenomena.
