Those limits include all water below 60 degrees south, and some of it, like the Arctic Ocean, is frozen. The world ocean is the principal component of Earth's hydrosphere, it is integral to all known life, forms part of the carbon cycle, and influences climate and weather patterns. The world ocean is the habitat of , known species, but because much of it is unexplored, the number of species that exist is much larger, possibly over two million. The origin of Earth's oceans remains unknown; oceans are thought to have formed in the Hadean period and may have been the impetus for the emergence of life.
