What characterizes the movement at divergent boundaries?

The movement at divergent boundaries is characterized by the separation of tectonic plates. This type of boundary occurs when two tectonic plates move apart from each other. As they separate, magma from the mantle rises to fill the gap, which can lead to the formation of new oceanic crust, typically seen in mid-ocean ridges. This process is known as seafloor spreading.

At divergent boundaries, the pulling apart of the plates creates new geological features like rift valleys and oceanic ridges. This movement is essential in the continual recycling of the Earth’s crust and plays a crucial role in the plate tectonics cycle. The separation of the plates at these boundaries can also result in volcanic activity, as the movement allows magma to escape to the surface. Understanding this fundamental aspect of divergent boundaries is critical for comprehending various geological formations and processes on Earth.
