You're very close! The area where two neighboring tectonic plates move away from one another is called a divergent boundary.

Here's why:

* Divergent means "moving apart".

* Boundary refers to the edge or line where the plates meet.

So, a divergent boundary is where two tectonic plates are pulling apart, creating space. This space can be filled with:

* Magma rising from the mantle, creating new crust (like at mid-ocean ridges)

* Volcanic activity

* Rift valleys

* Earthquakes
