The depth in the ocean where the rate at which calcareous sediments are supplied to the seabed equals the rate at which those sediments dissolve. What is this depth called?
A)calcium carbonate compensation depth
B)calcium dissolution depth
C)calcium carbonate pressure point
D)carbonate equalization depth

Question

Quizplus · Accepted Answer

This depth is called the calcium carbonate compensation depth (CCD). At this depth, the amount of calcareous material being deposited (from organisms such as plankton and shells) is balanced by the amount being dissolved by the water above due to pressures and chemistry factors. Below this depth, the rate of dissolution is higher than the rate of supply, resulting in a lack of calcareous sediments.
