The Whole History of the Earth and Life | Part 2 | Initiation of Plate Tectonics | Ascension Talks “The Whole History of the Earth and Life” is a documentary which portrays the birth of the solar system, the birth of the Earth, and the emergence and evolution of life on Earth depicted through our latest research activities. -------------------------------------------------------------- Chapter 2: Initiation of Plate Tectonics　(2nd edition) During 4.37-4.20 billion years ago, abundant icy planetesimals bombarded the primitive dry Earth, which caused it to be enveloped by an atmosphere and an ocean. After the appearance of ocean, plate tectonics started, but the ocean was too saline, acidic, and enriched in heavy metals. Life could not emerge in such a toxic ocean.
