Where Did Water Come From?

The video explores the origins of Earth's water, starting with a cataclysmic collision that formed the moon and set the stage for the Hadean aeon. It discusses how Earth's water likely came from meteorites, space, and solar winds, despite forming close to the sun where water is scarce. The video explains the role of chondrite meteorites and solar winds in delivering water to Earth, and how early Earth's atmosphere and oceans were different from today. It also delves into the isotopic composition of water, highlighting the differences between water in Earth's rocks and oceans, and the role of solar wind in creating light water. The complex journey of Earth's water is summarized, emphasizing its extraterrestrial origins and transformation over billions of years.
