water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area
Explanation:
The rift in east Africa is a divergent margin where two plates are moving away from one another.
Eventually, what will happen is that the separation will lead to the formation of a basin and the water from the nearby ocean will fill it up.
The proximal water body here are the water in the Indian Ocean.
The oceans of the world today were once together and the continents apart too.
When the continents started moving apart, the oceans filled the void left behind. This same process will occur in East Africa rift valley system.
