Divergent Plate Boundaries Use this PPT for p. 9 in your INB!  How they happen!

Divergent means: moving apart. “di-” means: two (think of divide or dissect)

Where in the World is this Boundary???

1. The Mid-Atlantic Ridge (or any mid- ocean ridge)

2. Iceland, which is splitting apart down the middle because it’s on the Mid- Atlantic ridge.

3. East Africa, which is splitting apart into thirds.

What are the resulting landforms of a divergent boundary???

(1) Rift Valleys The Álfagjá Rift Valley in southwest Iceland Most of the world’s rift valleys are on the ocean floor.

(2) Mid-Ocean Ridges (3) New Oceans (4) Volcanoes & (5) Shallow Earthquakes
