A mid-ocean divergent boundary is a type of geological feature which occurs where two plates are moving apart from each other. This type of boundary is typically found in the middle of the ocean, often near the Mid-Ocean Ridge. The movement of the plates creates new ocean crust which fills the gap between them. While there are several characteristics associated with this type of boundary, the following is not one of them:

• Mountain formation: This type of boundary does not result in the formation of mountain ranges like those found along continental boundaries.
• Volcanic activity: Mid-ocean divergent boundaries are not associated with volcanic activity.
• Earthquakes: Mid-ocean divergent boundaries are not typically associated with seismic activity.
• Trenches: While this type of boundary can occur near a trench, it is not the same type of boundary.

Mid-ocean divergent boundaries are primarily responsible for the creation of new ocean crust. This new ocean crust covers much of the ocean floor, and forms the foundations of the oceanic ridge system. As such, it is an essential part of the Earth’s crustal structure. Understanding the characteristics of this type of boundary is key to better understanding our oceans.
