Question

name the
rift valley
sea level
oceanic crust
lithosphere
100 km
asthenosphere
transform boundary
convergent boundary
sergent boundary
divergent boundary

Explanation:

A divergent boundary occurs when two tectonic plates move apart. In the image, there is a rift valley and the asthenosphere material is rising (indicated by the arrow). At divergent boundaries, new crust is formed as magma rises to fill the gap between the separating plates. Transform boundaries involve sliding past each other, convergent boundaries involve plates coming together (with one often sub - ducting), and "sergent boundary" is not a standard tectonic boundary term.

Answer:

D. Divergent Boundary
