Some types of plankton deposit calcium carbonate internally. Coccolithophores, for example, deposit internal skeletal like structures:
Emiliania huxleyi - Wikipedia, the free encyclopedia
When these organisms die, their bodies may drift down toward the bottom in the deep ocean.
When they reach a certain depth, the calcium carbonate begins to dissolve. This depth is called the lysocline.
Which of the following is not a reason that calcium carbonate becomes more soluble in the deep ocean than at the surface?
A. The magnesium concentration is higher
B. The pressure is higher
C. The temperature is lower
D. The pH is lower
Good luck!
