Unveiling the Salty Secret: Why 99.99% Don't Know Why Seawater is Salty

• Only 0.01% of Earth's water is drinkable, with the rest being salty seawater.
• Rainwater, slightly acidic from atmospheric carbon dioxide, dissolves rocks and soil, a process called rock weathering.
• Minerals like sodium and chloride from dissolved rocks are carried by rivers into the sea, accumulating over millions of years.
• Rivers remain fresh because their constant flow prevents high mineral concentration, unlike the sea which is a final collection point.
• Seawater evaporates, leaving salts behind, while evaporated water forms fresh rain, perpetuating the sea's salinity.
