compensation depth (CCD)?

W) Occurring between 2,000-3,000 m

X) Varying by latitude: deeper near the equator, shallower near the poles

Y) Restricted to waters near the poles in both hemispheres

Z) The depth at which carbonates start to form at nearly two times the rate of formation in shallower water
