How does the ocean act like a sink for carbon dioxide?
Atmospheric carbon dioxide dissolves in the water close to the surface of the ocean. As the amount of carbon dioxide in the atmosphere increases, therefore, so does the concentration of carbon dioxide in these surface waters. Most of the absorbed carbon is accommodated by chemical reactions between the water and carbon dioxide . But this 'buffering' capacity has limits and - if this water remains at the surface - it eventually becomes saturated with carbon dioxide. Surface water and deep water, however, are slowly but constantly overturning in a cycle of about 1000 years. As the surface waters move downwards - a process that occurs mainly in the North Atlantic and Southern oceans - it carries dissolved carbon dioxide down with it. As a result, about 75 per cent of the carbon that has been absorbed by the ocean since human activities began releasing carbon dioxide now resides in deeper waters. Overall, therefore, this process has recently been working as an important sink for carbon produced by human activity. Such downward transport, however, is relatively slow, and so it is ocean circulation - and not dissolution of carbon dioxide in surface waters - that limits carbon dioxide uptake by the oceans. Furthermore, models of the movement of oceanic water masses predict that in a warmer climate the sinking of surface water, and hence burial of carbon dioxide, will slow down, reducing the future role of the ocean as a carbon sink. Another way that the oceans absorb carbon is through the action of microscopic marine plants. When these organisms die, their bodies sink into deeper water. Although most of the carbon in the organisms decomposes to carbon dioxide before reaching the ocean floor, it is prevented from escaping back to the atmosphere (at least, until the oceans turn over). This biological uptake of carbon will probably increase in future, as changes in sea surface temperatures and chemistry lead to an increase in the growth of algae. But it will not be enough, however, to compensate for the reduced downward transport of water and dissolved carbon, and hence is unlikely prevent the overall ocean sink diminishing in the future. Inedeed sinks will probably never lead to a decrease in atmospheric carbon dioxide whilst carbon dioxide emissions continue at their current level.

What water will you not sink in because of the salt?
The body of water you will never sink in is The Dead Sea, because it has allot of salt and the salt will push you to the top of the water THEREFORE you WILL NOT sink.
Why do crayons sink?
All crayons are made of wax.Since wax float,all crayon should float.If crayons have heavy pigments in them, then they will sink in water. Metallic crayons will sink, and some glitter crayons as well.
What does 1.75 bathroom mean?
This indicates that it has a toilet, sink and a shower but no bathtub. A 1.50 indicates that it has a toilet, sink but no shower or bathtub.
What is kitchen sink music?
Probably music that is made using the clinks and clatters of washing things in the kitchen sink. Not sure though...:/
Is the ocean primarily a sink or source of carbon in the Earth's carbon cycle?
The ocean is primarily a sink of carbon in the Earth's carbon cycle.
What is the difference between a carbon source and a carbon sink in the context of the carbon cycle?
In the carbon cycle, a carbon source releases carbon dioxide into the atmosphere, while a carbon sink absorbs and stores carbon dioxide from the atmosphere.
What is the role of a sink in the carbon cycle?
The role of a sink in the carbon cycle is to absorb and store carbon dioxide from the atmosphere, helping to regulate the Earth's carbon balance. This process helps to mitigate the effects of climate change by reducing the amount of carbon dioxide in the atmosphere.
Is decaying vegetation a carbon sink?
Decaying vegetation is actually the opposite of a carbon sink. A carbon sink is something that takes carbon out its natural cycle and stores in for an extended period of time. Vegetation, particularly trees, absorb carbon, and thus they act as stores. However, decaying vegetation releases the carbon back into the air as it decays. Therefore, it is not a sink.
Why do scientist think there is a undiscovered carbon sink somewhere?
Scientists believe there may be an undiscovered carbon sink because current models do not fully account for all the carbon that is taken up by various ecosystems, such as forests or oceans. This missing carbon sink could help explain discrepancies in the global carbon budget and improve our understanding of the Earth's carbon cycle.
What is the process carried out by diatoms in the carbon cycle?
Diatoms play an essential role in the carbon cycle through photosynthesis. They take in carbon dioxide from the atmosphere and convert it into organic carbon compounds, releasing oxygen as a byproduct. When diatoms die, their remains sink to the ocean floor, where the carbon they have stored is effectively sequestered from the atmosphere for extended periods.
What process removes carbon dioxide from the atmosphere acting as a carbon sink?
Photosynthesis is a process that removes carbon dioxide from the atmosphere, acting as a carbon sink. During photosynthesis, plants absorb carbon dioxide and convert it into oxygen and glucose, which is then stored as biomass. This helps to reduce the amount of carbon dioxide in the atmosphere, balancing the carbon cycle.
How are heat sink and carbon sink related?
heat sink is when heat is absorbed into any type of environment, including the aquatic ecosystem; and carbon sink is when CO2 is absorbed into any type of environment including the terrestrial ecosystem.
Why you use a heat sink?
A heat sink increases the surface area of a hot item and increases the ability of the item to cool or be cooled.
Is coal a carbon sink?
No, coal is not a carbon sink. In fact, burning coal releases carbon dioxide into the atmosphere, contributing to climate change.
Is the ocean currently acting as a carbon sink or a carbon source?
The ocean is currently acting as a carbon sink, absorbing more carbon dioxide than it releases into the atmosphere.
When the atmosphere has too much carbon dioxide in it and the oceans absorb some of it to achieve a new balance This is an example of what?
This is an example of the carbon cycle, where carbon moves between the atmosphere, oceans, land, and living organisms. When the atmosphere has an excess of carbon dioxide, oceans act as a carbon sink by absorbing some of it, helping to regulate the balance of carbon in the environment. This process is important for maintaining Earth's climate and overall carbon balance.
