Identify two reasons why most lakes within the Rift Valley are salty?

Answer Text:
- Some lakes lack outlets.
- Rocks over which they lie / in contact with may contain mineral salts.
- Some rivers pouring in them may contain salts.
- Surface runoffs and rivers may dissolve a lot of salts on rocks while they flow.
- Excess evaporation in areas where the temperatures are high.
