Final Answer:
Divergent plate boundaries involve the separation of tectonic plates, leading to the formation of mid-ocean ridges where magma rises to create new oceanic crust. This process distinguishes divergent boundaries from other options, making the correct answer C.
Step-by-step explanation:
Divergent plate boundaries occur where tectonic plates move away from each other. This movement results in the formation of mid-ocean ridges, making option C the correct answer. Mid-ocean ridges are underwater mountain ranges formed by the upwelling of magma from the mantle, creating new oceanic crust as the plates separate. The process at divergent boundaries is characterized by volcanic activity and the continuous creation of oceanic lithosphere.
In these regions, magma rises to the surface, solidifies, and accumulates over time, contributing to the elevation of the mid-ocean ridge. This process, known as seafloor spreading, is integral to plate tectonics and the Earth's dynamic geology. The mid-ocean ridge system, which extends through various oceans, is a prominent example of divergent plate boundaries.
Unlike other options, such as subduction zones (option D) associated with convergent plate boundaries, divergent boundaries are not typically linked to intense seismic activity or the formation of mountain ranges. While earthquakes can occur at divergent boundaries, they are generally less powerful than those at convergent boundaries. Mid-ocean ridge accurately reflects the geological features and processes associated with divergent plate boundaries. Therefore the correct option is C).
