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 these boundaries, magma rises from the mantle and cools to form new crust. This newly formed crust is typically oceanic crust (made of basalt, denser and thinner), as most divergent boundaries occur at mid - ocean ridges. "Mountain crust" is not a recognized type of crust, and sedimentary crust is not formed at divergent boundaries in this typical way.

Answer:

oceanic crust
