Question

what type of crust is typically formed at divergent boundaries?
oceanic crust
mountain crust
sedimentary crust

Explanation:

Divergent boundaries are where tectonic plates move apart. At mid - ocean ridges (a type of divergent boundary), magma rises and cools to form new oceanic crust. "Mountain crust" is not a recognized type of crust, and sedimentary crust is not formed at divergent boundaries in this typical way. So the correct option is oceanic crust.

Answer:

A. oceanic crust
