HOW WEATHERING AND EROSION
AFFECT THE OCEANS SALINITY
ESS 8.8.10
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.
SALTS IN SEAWATER
CHLORIDE 55%
SODIUM 30.6%
SULFATE 7.7%
MAGNESIUM 3.7%
CALCIUM 1.2%
POTASSIUM 1.1%
OTHERS 0.7%
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.
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.
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.
