Plates pull apart at opposite direction at what kind of boundary?
divergent boundary
How is a new ocean going to split Africa in two in the future? (explain)
How is a new ocean going to split Africa in two in the future? (explain)
1. There is a divergent boundary in East Africa
2. The divergent boundary creates a Rift Valley
3. As the plates get further apart the Rift Valley will get deeper and wider
4. When the Rift Valley gets below sea level the Red Sea will fill it in
5. The new ocean will separate Africa into two continents.
