        NOVA: How to Create a Hydrothermal Vent

        Learn how scientists simulate hydrothermal vents to study how they may have contributed to the origin of life on Earth, in this video from NOVA Digital. As hydrothermal fluids flow from deep-sea vents, chimneys can form from the minerals in the water. Because hydrothermal fluid contains more electrons than the seawater surrounding it, an electrical current flows through the walls of the chimney. Electricity produced by hydrothermal vents in Earth’s ancient oceans could have provided the energy to spark the creation of amino acids, the building blocks of life. This resource is part of the NOVA: Web-Original Collection.
