Why do hot deserts have salt?

Answer 1

Hot deserts have salt due to the evaporation of water in arid conditions, which leaves behind dissolved minerals. When water from occasional rain or underground sources seeps to the surface and evaporates, it concentrates salts and minerals, creating salt flats or crusts. Additionally, the lack of vegetation prevents the leaching of these salts, allowing them to accumulate over time. These processes contribute to the characteristic saline environments found in many hot desert regions.
