Renewable energy from waves, tides, and currents. Structure of this class living ocean: physical ocean. Hydrogen formed shortly after the big bang. Oxygen was formed in stars that exploded before our sun was formed. Much of earth"s water was present in the nebula that coalesced into the sun and planets.
