This gas (name) combined with water start ocean acidification
Carbon dioxide
100
As salinity increases density ______________
increases.
100
CaCO3 is known as ___________
Calcium carbonate.
100
Since 1960 the amount of CO2 has ____________
increased
200
Organisms that use Calcium Carbonate are known as

200
The unit for salinity is o/oo. Which measures how many grams of salt per ___________ml(g) of water.
1000 ml 1000 g
200
CO3- is known as
Carbonate
200
Since 1960 the pH of the ocean has _______ making it more _______
Decreased, Acidic
300
The relationship between CO2 and pH is a ____________ relationship
indirect relationship
300
If you add 20 grams of salt to 2000 ml of water the salinity would be ______o/oo
10 o/oo
300
Carbonic acid is
H2CO3
300
The ocean absorbs ________ of our carbon dioxide
30% 1/4 (video)
400
Ultimately Ocean Acidification has to do with the ____ion (name) stealing _______(name)
Hydrogen (H+) and CO3-
400
If the salinity is 50 o/oo and you have 500 grams of water then you would have _________grams of salt..
25 grams of salt
400
HCO3 is
Biocarbonate
400
This layer is the the highest in salinity with no change to its density.
Deep water
500
If you increase CO2 then HCO3 will ________. Specifically HCO3 will causes (increase/decrease/no change) in pH.
Increase and No Change
500
Which of the following locations would have the highest salinity and why? 80 N 30 W 0 30 W 10S 30 W
80N because it is the furthest from the equator so less water evaporates from that location.
500
______ ion will steal _____ to create more ________ (all formulas)
H, CO3-, HCO3
500
If you had 1000g of sea water and take out 1/2 the amount of salt in it. The salinity would ________ by ________
decrease by 1/2
