(Hint: See next question No the thickness of ooze is not always an accurate indication because ooze does not accumulate everywhere on the ocean floor and because of the calcium carbonate compensation depth. 2. What is the calcium carbonate compensation depth? Is there a compensation depth for the siliceous components of once-living things? Calcium carbonate compensation depth is the rate at which calcareous sediments are supplied to
