Question:

With respect to controlling atmospheric carbon dioxide, the "solubility pump" is most important:

a. in the deep ocean

b. in the surface ocean

c. at hydrothermal vents

d. at the oxygen minimum

Oceans:

Oceans possess diverse features. They are described as the major basis of precipitation and moisture occurring in the atmosphere. They also act as a home for an extensive range of aquatic and marine animals.

Answer and Explanation: 1

In terms of controlling atmospheric carbon dioxide, the solubility pump is significant in the deep ocean. This is because the solubility of CO2 in seawater tends to upsurges with declining in temperature. Therefore, the solubility pump exhibits its working by transferring CO2 to the deep sea or deep ocean.

Therefore, the correct answer is A.

  • Option B. is incorrect as in terms of atmospheric carbon dioxide, the solubility pump is not significant for surface ocean
  • Option C. is incorrect because the solubility pump is not significant for the hydrothermal vents in terms of atmospheric carbon dioxide.
  • Option D. is incorrect as in terms of atmospheric carbon dioxide, the solubility pump is not significant for minimum oxygen.
