Ocean A large body of salt water which covers about ¾ of Earth A large amount of freshwater is formed by the water cycle over the oceans. Water pressure increases as you go deeper into the oceans. ocean

Salinity The amount of salt dissolved in water Extreme Salinity! Ocean water is more dense than freshwater because of the dissolved salts. http://www.deadsea.co.il/ENA/Picture_Gallery/Nof.htm Extreme Salinity! – the Dead Sea

Tide Repeated rise and fall in the level of the ocean High tide Low tide
