OCEAN SALINITY, TEMPERATURE AND DENSITY
USE YOUR NOTES AND RAISE YOUR HANDS PLEASE. Review Questions Ocean floor features
SALINITY Calculated as mass of salt/mass water Most sea water is 3.5%
PRACTICE What mass of salt would make a concentration of 10% salinity in 500g of water?
WHERE DOES THE SALT COME FROM? Chemical weathering of rocks on the continents. volcanic eruptions
PROCESSES THAT AFFECT SALINITY Addition of freshwater- how does this happen? Reduction of freshwater- what causes this?
WOULD SALINITY BE GREATER OR LESS THAN 3.5% HERE?
OCEAN TEMPERATURE Primarily a function of latitude
TEMPERATURE ALSO VARIES WITH DEPTH.
WHAT DO YOU THINK THAT GRAPH MIGHT LOOK LIKE IN THE POLAR REGIONS? SKETCH IT IN YOUR NOTES.
SEA WATER DENSITY Influenced by temperature and salinity Temperature is the most important variable here.
QUESTIONS What is the effect of increasing temperature? What is the effect of increasing salinity?
OCEAN LAYERING surface zone-warmest -solar radiation-300m 2% water transition zone-temp goes down following the thermocline18% water deep zone-no sun, cold 80% of ocean
Properties of Ocean Water
Ocean Water and Ocean Life
Lesson 7: Ocean Layers II Physical Oceanography. Last class we learned about salinity How is salinity measured? How does salinity affect the density of.
Ocean Structure and Circulation 1. Ocean Model Temperature Depth Surface Deeper WarmerColder 2.
Clines Cline means ‘rapid change in’ Thermocline is a rapid change in temperature Pycnocline is a rapid change in density.
Influenced by: Weather/Wind Positions of the continents Rotation of the Earth Sun, Salinity, Density.
Oceans: Temperature, Composition, Structure, & Currents.
The Oceans Composition. The Oceans There are five main oceans: –Pacific, Atlantic, Indian, Arctic, Antarctic.
Earth Science: 15.1B Ocean Water and Life
9.1 Oceans. The Blue Planet 71% of Earth’s surface is covered by oceans and seas. The science that studies the world ocean is called oceanography. Question:
The Composition of Seawater
Guided Notes about Seawater
EARTH SCIENCE Prentice Hall EARTH SCIENCE Tarbuck Lutgens
Section 1: Properties of Ocean Water
15.1 Composition of Seawater. The total amount of solid material dissolved in water Mass of dissolved substances : Mass of the water sample Shown.
