Earth Science Water: universal solvent, dissolving 57 of the 92 elements on Earth Salinity: every solid dissolved into the ocean’s water Seven elements account for >99% of dissolved solids in seawater ~ Cl, Na, Mg, S, Ca, K, Br Express Salinity: %, ppm, mg/L, g/kg, pp(thousand) The most common notation: parts per thousand ( o/oo) Tropics: 34.5% (Brackish water – salinity of less than 35%) Subtropical: 36% (Brine) Why is there such a difference? Rainfall ~ which is freshwater Vertical Structure of Earth’s Oceans 2% ~ Mixing Zones: 1. Wind/Wave/Currents 2. Sun 18% ~ Thermocline Transaction: transitioning b/w the warm & cold temperatures 80% ~ Deep Cold Zone: 30° 33°F (salt water) Influences on the Coastline: Solar Energy: creating weather/climate Wind: generates ocean currents/ waves Climate The Coastline Environment is call the Littoral Zone Includes some of the land 200 meters worth of water Shore: where the ocean & land meet Coast: just the land part of the environment, NOT the water Beach: the part of the coastline that is in constant flow/movement MSL (Mean Sea Level): average tidal wave level Ocean Topography: oceans aren’t necessarily flat Tides: sun’s and moon’s gravitational pull
