About Ocean and Water
Ninety percent of all water on Earth is in the seas, greater part in the Pacific which covers half the planet and is bigger than all the landmasses put together........... AS Phillip Ball notes,we would better call our planet not Earth but Water...... Of the 3 % of the Earth`s water that is fresh, most exist as ice sheets....... Just 0.001 % exist in cloud or vapour........ If all the water in the atmosphere fell as rain and evenly everywhe3re the ocean would deepen only by one inch.
The eastward spin of the earth piles water up against the ocean`s western margin
Institutional World mostly ignored the Sea and deep water exploration began in 1830.
