  1. HOW WEATHERING AND EROSION AFFECT THE OCEANS SALINITY ESS 8.8.10

  2. OCEAN SALINITY • OCEAN WATER CONTAINS MANY DIFFERENT DISSOLVED SALTS. • THESE SALTS COME FROM RIVERS AND GROUNDWATER SLOWLY DISSOLVING ELEMENTS SUCH AS CALCIUM, MAGNESIUM, AND SODIUM FROM ROCKS AND MINERALS. • RIVERS TRANSPORT THESE ELEMENTS TO THE OCEAN. • ERUPTING VOLCANOS ADD ELEMENTS, SUCH AS SULFUR AND CHLORINE TO THE ATMOSPHERE AND OCEANS.

  3. SALTS IN SEAWATER CHLORIDE 55% SODIUM 30.6% SULFATE 7.7% MAGNESIUM 3.7% CALCIUM 1.2% POTASSIUM 1.1% OTHERS 0.7%

  4. OCEAN SALINITY • RIVERS THAT FLOW TO THE OCEAN DISSOLVE SODIUM ALONG THE WAY. • VOLCANOES ADD CHLORINE GAS. • MOST OF THE SALT IN SEAWATER IS MADE OF SODIUM AND CHLORINE. • ALTHOUGH RIVERS, VOLCANOES, AND THE ATMOSPHERE CONSTANTLY ADD SUBSTANCES TO THE OCEAN, THE OCEANS ARE CONSIDERED TO BE IN A STEADY STATE.

  5. OCEAN SALINITY • AS NEW SUBSTANCES COME IN, ELEMENTS ARE REMOVED FROM SEAWATER BY BIOLOGICAL PROCESSES AND BY BECOMING SEDIMENT. • SEA ANIMALS AND ALGAE USED DISSOLVED SUBSTANCES. • MARINE ANIMALS USE CALCIUM TO FORM BONES. • OTHER ANIMALS, SUCH AS OYSTERS AND CLAMS, USE CACIUM TO FORM SHELLS.

  6. OCEAN SALINITY • SOME ALGAE, CALLED DIATOMS, HAVE SILICA SHELLS. • BECAUSE MANY ORGANISMS USE CALCIUM AND SILICA, THESE IONS ARE REMOVED MORE QUICKLY FROM SEAWATER THAN ARE SUBSTANCES SUCH AS CHLORIDE OR SODIUM. • IRON IS REMOVED MORE QUICKLY BECAUSE IRON FORMS SOLIDS THAT FALL TO THE OCEAN FLOOR. • VOLCANOES, GROUNDWATER AND RIVERS ADD SALTS TO SEAWATER.
