1. HOW WEATHERING AND EROSION AFFECT THE OCEANS SALINITY
ESS

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 %
CALCIUM %
POTASSIUM %
OTHERS %

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.
