What does carbon do in water?
It sinks
What is solubility?
ability of something to be dissolved
What is the only substance that can be found naturally in all three states?

What is coral bleaching?
When the temperatures go above normal
CO2 helps _____ acidity.
Buffer
What is under-saturated water?
water that can hold more dissolved gas
Why does water clump together in drops rather than spreading out in a thin film?
It has very high surface tension.
What is it called when you make a conclusion based on evidence and reasoning?
Inference
What are Tidal Pools?
They are pools of salty water uncovered during the low tides.
What are the CO2 sources?
Respiration and decay
What is ‘saturation value?’ (_____→_____)

Water is attracted to other molecules because of...
Cohesion
What is the difference between a constant and the control?
A constant is a factor in the experiment that doesn’t change. A control is an element that remains unchanged by other variables.
What is the movement of water driven by differences in salinity?
thermohaline circulation
What is the neutral on the pH scale?

What abiotic deep water structures add gas?
volcanic (hydrothermal) vents
What is the movement of water within the spaces of a porous material due to the forces of adhesion and cohesion?
Capillary Action
What is Empirical Evidence?
Data produced from an experiment.
What are Red Tides?
When there are numerous amounts of dinoflagellates that the water becomes red due to accessory pigments.
Acidity- pH in relation to Hydrogen looks like what?
Acidic= extra Hydrogen
Basic= extra Hydroxides
Neutral= pH 7
Dead zones are?
regions of decreased productivity due to less Oxygen in the water.
