Answer 1

Hello Olivia!!! 

Q.) Describe at least two geological events that can occur at a divergent boundary.

A.)Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill.

Hope this can help!!!
