Question

1. what would you be most likely to find at a divergent boundary between two pieces of oceanic crust? rift island arc mid - ocean ridge flat land

Explanation:

A divergent boundary between two pieces of oceanic crust is a place where tectonic plates are moving apart. Mid - Ocean Ridges are formed at such boundaries. A rift is more associated with continental crust divergence. An island arc forms at convergent boundaries (subduction zones). Flat land is not a typical feature of oceanic crust divergent boundaries.

Answer:

Mid - Ocean Ridge
