@Hang2021Zhou @CryptoMichNL As the molten outer layer of Earth cooled it formed the first solid crust, which is thought to have been mafic in composition. The first continental crust, which was more felsic in composition, formed by the partial melting of this mafic crust.
@TastyBonsai @Alphawolf_1_@Revolotto Earths atmosphere and oceans were formed by volcanic activity and outgassing. Water vapor from these sources condensed into the oceans, augmented by water and ice from asteroids, protoplanets, and comets. Sufficient water to fill the oceans may have been.
@Inosuke_Kuru @TheBitcoinConf However, many of the physical properties of water and ice are controlled by the formation of hydrogen bonds between adjacent oxygen and hydrogen atoms while it is a weak bond, it is nonetheless critical in controlling the structure of both water and ice.
