What is the difference between CCD and CCD in geology?

CCD refers to the ocean depth at which calcium carbonate is present only in solution. 1. True 2. False - 14311894

What is CCD (carbonate compensation depth)?

It is the CALCITE COMPENSATION LEVEL (CCD). In areas deeper than the CCD, only clay or siliceous sediments are deposited and carbonates and carbonated fossils are absent. Lysocline and CCD vary in depth today in each ocean, being greater in the tropical belt (up to 5000 m). The CCD for the same latitude has varied throughout geological time.

What is the difference between CCD and calcite?

The carbonate compensation depth, or CCD, is defined as the water depth at which the rate of supply of calcium carbonate from the surface is equal to the rate of dissolution. As long as the ocean floor lies above the CCD, carbonate particles will accumulate in bottom sediments, but below, there is no net accumulation.

What is the difference between CCD and ACD?

The carbonate compensation depth, or CCD, is the depth in water where the rate of calcium carbonate supply from the surface equals the rate of dissolution. Carbonate particles will build in bottom sediments as long as the ocean floor is above the CCD, but there will be no net accumulation below dominant.

What depth is CCD found?

In today's oceans, the CCD is between 4 and 5 kilometers deep. It is deeper in places where new water from the surface can flush away the CO2-rich deep water, and shallower where lots of dead plankton build up the CO2.Sep 24, 2018

What is the CCD in the ocean?

calcite compensation depth (CCD), in oceanography, the depth at which the rate of carbonate accumulation equals the rate of carbonate dissolution. The input of carbonate to the ocean is through rivers and deep-sea hydrothermal vents.

What is the CCD and why is there usually no calcite deposits below that depth?

The calcite compensation depth (CCD) is the depth in the oceans where the rate of calcium carbonate material forming and sinking is equal with the rate the material is dissolving. Below the CCD no calcium carbonate is preserved—generally there is no CaCO3 beneath about 15,000 feet (4500 meters) (Figure 6.81).Feb 14, 2021

How is the carbonate compensation depth CCD related to the worldwide distribution of calcareous oozes?

The carbonate compensation depth (CCD) is the dominant facies boundary on the deep-sea floor. It separates calcareous from noncalcareous sediments, with the calcareous deposits (“carbonate ooze”) restricted roughly to the shallower half of the deep-sea floor.May 20, 2016

What controls the depth of the CCD?

The depth of the CCD is mainly controlled by two factors: the degree of undersaturation with respect to calcite or aragonite and the flux of CaCO3 debris from the surface.Jul 18, 2018

What is the approximate depth of the calcite compensation depth CCD in the ocean quizlet?

The Calcite Compensation Depth (CCD) is the depth in the ocean where carbonate dissolution equals carbonate supply. The CCD, on average, is 4500 meters below sea level. Below this level, sediment does not usually contain much calcite because it readily dissolves.

What occurs below the calcium carbonate compensation depth quizlet?

the depth at which the rate of accumulation of calcareous sediments equals the rate of dissolution of those sediments. Below this depth, sediment contains little or no calcium carbonate.

What is the calcium carbonate compensation depth is there a compensation depth for the siliceous components of once living things?

What is the calcium carbonate compensation depth? Is there a compensation depth for the siliceous components of once living things? The depth in the oceans below which the rate of supply of calcite lags behind the rate of solution, such that no calcite is preserved.

What is lysocline and CCD?

The lysocline and carbonate compensation depth (CCD) are two phenomena that affect the stability of calcite and aragonite in the deep ocean. The lysocline is the depth at which the rate of dissolution of calcite begins to increase dramatically.Nov 6, 2020

What is the carbonate compensation depth CCD and how does it affect deep sea sedimentation?

Carbonate compensation depth (CCD) is the depth in the oceans below which the rate of supply of calcite (calcium carbonate) lags behind the rate of solvation, such that no calcite is preserved.

What is the carbonate compensation depth quizlet?

What is the Carbonate Compensation Depth (CCD)? Calcium Carbonate Compensation Depth (CCD) the depth at which the rate of accumulation of calcareous sediments equals the rate of dissolution. Be able to describe why calcareous oozes (CaCO3) are not found in the deep ocean bottom.

What is the compensation depth in the ocean when primary productivity is discussed?

The depth at which primary production equals respiration is called the compensation depth. Above this depth, phytoplankton can make a living; below this depth, they cannot and either die or go into a resting stage to await better light conditions. They can live but cannot grow or reproduce.Mar 5, 2010
