Why are most Rift Valley lakes salty?
The rains chemically interact with rift terrains, which are dominated with natrocarbonatitic volcanic materials, thus transporting dissolved salts to the lakes. In addition, hot springs around the shores of these lakes carry significant salinity loads into the lakes.
What will happen to the Great Rift Valley in Africa eventually?
Eventually the rift should expand and break Africa into two continents: The smaller continent will include present-day Somalia and parts of Kenya, Ethiopia, and Tanzania, while the bigger one will include everything else.
