Currently the ocean has a pH of ___ and is ________
Approximately 8, Basic

Definition of salinity
The measure of all the salts dissolved in water.
100
What are the two types of currents.
What are surface and deep.

What is the longest Mountain Range in the world?
Mid Ocean Ridge, 65,000 KM. BENEATH THE OCEAN!
200
This layer/zone is the largest in the ocean
Deep, >80%
200
The ocean absorbs _____ from the atmosphere. What is this process called?
CO2, Carbon Sequestration
200
The salinity of the ocean is _____________ throughout the world.
heterogeneous, no homogenous
200
Surface currents are influence by:
Winds, Weather, Eath's Rotation
200
This is the name of deepest part of the ocean
What is the marina trench, at a depth of 6.83 miles
300
Define halocline, thermocline, pycnocline
The pycnocline encompasses both the halocline (salinity gradients) and the thermocline (temperature gradients) and refers to the rapid change in density with depth. Because density is a function of temperature and salinity, the pycnocline is a function of the thermocline and halocline.
300
Name the two factors that influence how much any gas the ocean can absorb.
Temperature, Salinity
300
Salinity is usually described in this unit of measurement.
parts per thousand, PPT
300
Deep ocean currents are influence by:
Density differences: salinity, temperature
400
In these areas the pycnocline shows the smallest change.
High lattitudes, poles, artic
400
CO2 and H2O combine to make _______
Carbonic Acid, H2CO3
400
List the three factors that influence ocean salinity.
Precipitation, Evaporation, Melting, Rivers, Geography
400
Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called __________.
Coriolis Effect
500
Draw models of the Halocline, Themocline, Pycnocline with respect to ocean depth.

Write the chemical formulas for the following chemical compounds: Water Carbon Dioxide Carbonate Bicarbonate Calcium Carbonate
H20 C02 CO3 2- HCO3 - CaCO3
500
This ocean is the saltiest
Surface waters in the Atlantic have the highest salinity, higher than 37 parts per thousand in some areas. This is because, on average, there is more evaporation than combined rainfall and river runoff into the Atlantic Ocean, maintaining higher salinity than in the other basins.
