When carbon enters the deep ocean how long dies it stay there?
When carbon enters the deep ocean, it can remain there for hundreds to thousands of years. This long residence time is due to the ocean's layered structure, where deep waters are less accessible to mixing with surface waters. The carbon is part of the ocean's carbon cycle, contributing to the long-term storage of carbon in the deep sea. Ultimately, processes such as upwelling and ocean circulation can eventually return this carbon to the surface, but this can take a significant amount of time.
How much does the deep sea ocean account for the earths carbon?
The deep sea ocean plays a significant role in the Earth's carbon cycle, storing approximately 38,000 gigatons of carbon, which is more than the atmosphere and terrestrial ecosystems combined. This vast reservoir helps regulate global climate by sequestering carbon dioxide through processes like the biological pump, where marine organisms absorb CO2 and transport it to the ocean depths upon their death. The deep ocean effectively acts as a long-term carbon sink, influencing both ocean chemistry and climate systems.
What is a deep ocean trenches?
A deep ocean trench is a deep underwater canyon. It is found at the deepest parts of the ocean. It is long, thin, and has steep sides.
What are deep-ocean trenches?
Deep ocean trenches are deep slits in the middle of the ocean. The pressure inside these trenches is unbearable. long, curved valleys along the edges of the ocean basin
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 cycle of carbon in seawater?
The carbon cycle in seawater involves the absorption of atmospheric carbon dioxide (CO2) by the ocean, where it dissolves and reacts with water to form carbonic acid. This process leads to the formation of bicarbonate and carbonate ions, which are utilized by marine organisms for processes like photosynthesis and shell formation. Carbon is also exchanged between the ocean and the atmosphere through various biological and physical processes, including respiration, decomposition, and ocean currents. Ultimately, carbon can be sequestered in deep ocean sediments, helping to regulate global carbon levels over long periods.
What role does the carbon reservoir def play in the global carbon cycle?
The carbon reservoir in the deep ocean plays a crucial role in the global carbon cycle by storing and releasing carbon dioxide over long periods of time. This helps regulate the amount of carbon dioxide in the atmosphere, which is important for maintaining Earth's climate and overall balance of carbon in the environment.
How is carbon stored in surface ocean?
Carbon is stored in the surface ocean primarily through two processes: the dissolution of atmospheric CO2 and the biological pump. When CO2 from the atmosphere enters the ocean, it reacts with water to form carbonic acid, which dissociates into bicarbonate and carbonate ions, effectively storing carbon in dissolved forms. Additionally, phytoplankton absorb CO2 during photosynthesis, converting it into organic matter, which can be further transferred to deeper waters when these organisms die or are consumed, contributing to long-term carbon storage.
Is a mid ocean ridge a long narrow depression located in a deep ocean basin true or false?
false
What are the characteristics of ocean trench?
An ocean trench is a long, deep depression in the ocean. They are the result of oceanic plates sliding under one another.
What is a 3 dimensional object that is long wide and deep?
a pool, a building, the ocean.
A long narrow and very deep canyon where the ocean floor bends toward the mantle is called what?
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.
