What are divergent plate boundaries and their significance?
Understand the Problem
The question is asking for information regarding divergent plate boundaries, particularly their mechanisms and significance in oceanic formation.
Answer
Zones where tectonic plates move apart, causing earthquakes and creating new oceanic crust, such as the Mid-Atlantic Ridge.
Divergent plate boundaries, where two tectonic plates move apart, are characterized by seismic activity and the formation of new oceanic crust as magma rises to the surface, exemplified by mid-ocean ridges like the Mid-Atlantic Ridge.

More Information
Divergent plate boundaries are significant in geological studies as they provide insights into the processes of seafloor spreading and the cyclical nature of crust formation and destruction. They also help scientists understand the dynamics of Earth's lithosphere.
Tips
A common mistake is confusing divergent boundaries with convergent boundaries, where plates move towards each other. It's crucial to remember that divergent boundaries involve the creation of new crust while convergent boundaries involve the destruction or deformation of crust.
