Oxygen Therapy: Indications & Patient Management

Scientists have made a surprising discovery showing that some rocks on the deep ocean floor can produce oxygen in complete darkness, without photosynthesis or sunlight. • The rocks are located on the deep-sea floor, far below sunlight penetration. • They generate tiny natural electric currents through chemical reactions. • These micro-currents can split seawater (H₂O) into hydrogen and oxygen. • The process is known as electrochemical water splitting, occurring naturally. • Oxygen is produced wi

The oldest rocks on Earth are over 4 billion years old — but the materials that formed them are even older! 🧓 Common chemical elements in rocks, like oxygen and silicon, were made by stars that exploded before our solar system formed. More: https://go.nasa.gov/4fTTUel #OldRockDay | NASA Universe
