- The carbon cycle is the set of biogeochemical processes by which carbon undergoes chemical reactions, changes form, and moves through different reservoirs on earth, including living organisms.
- The geological component of the carbon cycle is driven by plate tectonics and includes processes like volcanic eruptions and burial of carbon-rich sediments on the ocean floor.
- The biological component of the carbon cycle is driven by respirationand photosynthesis by living organisms.
- Humans influence the global carbon cycle in several ways, but primarily through burning fossil fuels.

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 would cause heart rate to slow down while having flue?
You typically have a slow heart rate when you are at rest. When you have the flu, you really don't get out of bed during this time, so it is normal to have a slower heart rate.
How can you slow your heart rate to breathe underwater?
imagine how you usually breathe..... ....do that, only slower.
What will happen if there will be no forests on earth .How will it impact us?
As we all know that forests are necessary for the earth. Forests and plants give us oxygen to breathe. Without them we would die. That's why people are working so hard to stop/slow down Global Warming. The world is a cycle and without trees and forests, the ecosystem will no longer be a cycle and many things will no longer exist.
Why is your Nissan primastar slow to start and slow to rev up when cold?
slow to start from cold and starts when warm
What is the difference between fast and slow parts in the carbon cycle?
The fast carbon cycle involves processes that occur relatively quickly, such as photosynthesis, respiration, and the exchange of carbon dioxide between the atmosphere and oceans. In contrast, the slow carbon cycle involves processes that take longer, like the weathering of rocks and the formation of sedimentary rocks, which sequester carbon over millions of years.
How does the slow carbon cycle contribute to the overall balance of carbon in the Earth's atmosphere and ecosystems?
The slow carbon cycle helps maintain the balance of carbon in the Earth's atmosphere and ecosystems by storing carbon in rocks, soil, and the ocean over long periods of time. This process helps regulate the amount of carbon dioxide in the atmosphere, which is important for maintaining a stable climate and supporting life on Earth.
Which biogeochemical cycles is a slow cycle which involves the erosion of rocks?
The phosphorus cycle is a slow cycle that involves the erosion of rocks. Phosphorus is released from rocks through weathering and erosion processes over long periods of time, making it a slow process compared to other biogeochemical cycles like the carbon cycle or nitrogen cycle.
Why is carbon important in the carbon cycle?
They break down organic remains such as dead plants and animals into small particles. This slow decaying process is the beginning of CARBONIFICATION which turns these particles into fossil fuels. The bacteria also return carbon to the atmosphere in the form of Carbon Dioxide during RESPIRATION.
State of amphibians in which body activities slow during the winter?
hybernation
How can the carbon cycle be used to slow down global warming?
The carbon cycle is the natural way of moving carbon in and out of the atmosphere. The only way it could be used to slow down global warming would be if we planted billions of trees. Trees use photosynthesis to remove carbon dioxide from the air.
Does a koala's metabolism slow down during part of the year?
No. The koala's metabolism remains consistent throughout the year. It does not need to slow down during winter.
Where is the carbon cycle naturally slowest?
The carbon cycle is naturally slowest in deep ocean waters, where carbon can remain sequestered for hundreds to thousands of years before resurfacing. In these regions, carbon can be stored in deep-sea sediments, forming long-term repositories of carbon that contribute to the slow turnover of carbon in the cycle.
What is the difference between the short and long carbon cycle?
The difference between the short and long carbon cycle is that the short cycle emphasizes the interaction between the biosphere and atmosphere while the long cycle emphasizes the formation and destruction of fossil fuels.
Why do people love winter?
Bears hibernate, and moisture is collected for a slow drip during the spring thaw. The Winter Olympic Games, and sledding.
Food remains fresh for a longer time during winter Why?
cold temperatures slow decay
Why does the panda walk slow?
Pandas walk slow to conserve energy and since it can be cold in China during the winter their conserved energy helps them to survive
