If every river that flows into the sea is fresh water, how did the ocean become so salty? This video dives into "The Deep Chemistry of Oceanic Salinity," revealing the 4-billion-year-old process that turned our oceans into a vast chemical reservoir. 🌊
We track the journey of rain as it turns acidic, dissolves the continents, and transports minerals into the sea, while underwater volcanoes add to the mix from below.
In this video, you will discover: 🌧️ The Acid Rain Cycle: How rainwater slowly erodes mountains and carries dissolved rocks into the ocean. 🌋 The Floor is Leaking: The massive role of underwater hydrothermal vents in pumping ions into the water. ⚖️ The Balance: Why the ocean doesn't get infinitely salty (the natural "sinks" that remove minerals). 🌍 Climate Control: How this salty mixture is actually fundamental to regulating the planet's temperature.
Are we swimming in water, or liquid rock?
