Liberal Studies Assignment

Which of the following is a primary conclusion of the article?

a. Increasing atmospheric CO2 contributes to both OA and temperature increase/buffering,

therefore it is critical to consider the interaction between numerous complex variables when

generating models and making predictions regarding global warming.

b. “The concept of global warming was created by and for the Chinese in order to make U.S.

manufacturing non-competitive.”

c. The increasing global temperature due to CO2/green house gas effects sufficiently decreases the

solubility of CO2 in water to such an extent that we don’t really need to worry about OA.

d. CO2 solubility in water is largely temperature independent so temperature will only influence the

acid-base equilibrium in the ocean.

e. Climate has been changing throughout earth’s history so therefore the habits of 7.6 billion

humans have minimal influence on OA or temperature buffering effects.

Which of the references would you read to learn more about OA and how it relates to major extinction

events for marine calcifiers?

a. Hönish et al., 2012

b. Johnson, 1982

c. Lough et al., 2000

d. Otto et al., 2013

e. Zeebe et al., 2001

Equation 3, CO2(g) <-> CO2(aq), is an example of a:

a. chemical equilibrium

b. homogeneous equilibrium

c. heterogeneous equilibrium

d. sublimation

In the article they describe concentrations (i.e. [HCO3-]) in units of mol/kg. For species in [brackets],

what concentration unit do we typically use in chemistry?

a. g/mol

b. mol/L

c. g/L

d. lbs/gallon

Increasing atmospheric and ocean temperatures decreases the impact of OA:

a. true

b. false
