Osmosis and Reverse Osmosis
Description
The process of osmosis involves the movement of a solvent through a semipermeable membrane to balance solute concentrations, a mechanism that is critical to the function of biological cells. This video explores the physical principles behind the phenomenon and explains how applying external pressure enables reverse osmosis—a process vital for seawater desalination and water purification.

Why Is the Ocean Salty?
Credit: מכון דוידסון לחינוך מדעיThe salinity of the oceans stems primarily from the erosion of rocks on land by slightly acidic rain, which dissolves minerals and carries them through rivers into the sea. As water evaporates from the ocean surface, these salts are left behind, their concentration steadily increasing over billions of years. Additional sources of salt include hydrothermal vents on the seafloor and underwater volcanic activity.2:33
