Two types of Divergent Plate Boundaries

Divergent plate boundaries occur when two tectonic plates move away from one another.
Divergent plate boundaries are considered constructive boundaries.
If you look at a map of the major tectonic plates you can see several divergent plate boundaries.
There are two major types of divergent boundaries.
Continental and continental lithosphere and oceanic and oceanic lithosphere.
An example of an oceanic and oceanic divergent boundary is the mid-ocean ridge.
The mid-ocean ridge runs around the world including going right through Ice land.
A famous example of a continental and continental divergent boundary is the African rift valley.
