Mountain building processes result in the return of this geologic carbon to the Earth's surface. There the rocks are weathered and carbon is returned to the atmosphere by degassing and to the ocean by rivers. Other geologic carbon returns to the ocean through the hydrothermal emission of calcium ions. In a given year between 10 and 100 million tonnes of carbon moves around this slow cycle. This includes volcanoes returning geologic carbon directly to the atmosphere in the form of carbon dioxide. However, this is less than one percent of the carbon dioxide put into the atmosphere by burning fossil fuels. − − 慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。 − − ==Deep cycles 深层循环== − {{further|Deep carbon cycle}} − − The terrestrial subsurface is the largest reservoir of carbon on earth, containing 14–135 [[Orders of magnitude (mass)|Pg]] of carbon{{hsp}}<ref>{{cite journal |doi = 10.1111/1574-6941.12196|title = Weighing the deep continental biosphere|year = 2014|last1 = McMahon|first1 = Sean|last2 = Parnell|first2 = John|journal = FEMS Microbiology Ecology|volume = 87|issue = 1|pages = 113–120|pmid = 23991863}}</ref> and 2–19% of all biomass.<ref>{{cite journal |doi = 10.1073/pnas.1203849109|title = Global distribution of microbial abundance and biomass in subseafloor sediment|year = 2012|last1 = Kallmeyer|first1 = J.|last2 = Pockalny|first2 = R.|last3 = Adhikari|first3 = R.

'''生物地球化学循环 biogeochemical cycle'''是化学物质在地球的生物隔室和非生物隔室中进行循环（被转化或穿过）的过程。生物隔室指生物圈，非生物隔室指大气圈、水圈和岩石圈。其包括化学元素的生物地球化学循环，如钙、碳、氢、汞、氮、氧、磷、硒、铁和硫，以及分子循环，如水和硅。同时也包括宏观循环，如岩石的循环，以及人为诱导的合成化合物的循环，如多氯联苯（PCBs）的循环。某些循环中存在有储库，储库能使一种物质得以长时间保留或被隔离。

能量在生态系统中定向流动，以阳光（或化能自养生物的无机分子）的形式进入，并在营养级之间的众多转移过程中以热量的形式离开。然而，组成生物体的物质是被保存和循环利用的。与有机分子相关的六种最常见元素——碳、氮、氢、氧、磷和硫——以各种化学形式存在，并可能长期存在于大气、陆地、水体或者地表以下。地质过程，如风化、侵蚀、排水和大陆板块的俯冲，都在这种物质循环中发挥作用。由于地质学和化学在对于该过程的研究中起主要作用，无机物在生物体及其环境之间的循环便被称为生物地球化学循环。<ref name=OpenStax>[https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles Biogeochemical Cycles] {{Webarchive|url=https://web.archive.org/web/20210927040316/https://cnx.org/contents/ZdFkREJc@7/Biogeochemical-Cycles |date=2021-09-27 }}, ''OpenStax'', 9 May 2019.

上述的六种元素以多种方式被生物体利用。氢和氧存在于水和有机分子中，这两种分子对于生命都是必不可少的。所有的有机分子都含有碳，而氮是核酸和蛋白质的重要成分。磷被用来制造核酸和构成生物膜的磷脂。硫对于蛋白质的三维形态至关重要。这些元素的循环是相互关联的。例如，水的流动对于硫和磷渗入河流并流入海洋是至关重要的。矿物质在生物和非生物成分间循环，并从一个生物体转移到另一个，从而在生物圈中进行循环。<ref name=Fisher2019>Fisher M.

The living factors of the planet can be referred to collectively as the biosphere. All the nutrients—such as carbon, nitrogen, oxygen, phosphorus, and sulfur—used in ecosystems by living organisms are a part of a closed system; therefore, these chemicals are recycled instead of being lost and replenished constantly such as in an open system.
在生态系统中有很多生物地球化学循环过程作为系统的一部分运作，如水循环、碳循环、氮循环等等。生物体中所有的化学元素都是生物地球化学循环的一部分。除了作为生物体的一部分，这些化学元素还在生态系统的非生物因子中循环，如水（水圈），陆地（岩石圈）和/或空气（大气圈）。<ref name="enviroliteracy.org">{{cite web|title=Biogeochemical Cycles|url=http://www.enviroliteracy.org/subcategory.php/198.html|publisher=The Environmental Literacy Council|access-date=20 November 2017|archive-date=30 April 2015|archive-url=https://web.archive.org/web/20150430133927/http://enviroliteracy.org/subcategory.php/198.html|url-status=live}}</ref>
地球上的生命因素可以统称为生物圈。生态系统中生物体使用的所有营养物质，如碳、氮、氧、磷和硫，都是封闭系统中的一部分。因此，这些化学物质会被循环利用，而不是像在开放系统中那样不断丢失和补充。<ref name="enviroliteracy.org"/>
右图展示了一个广义的生物地球化学循环。生物圈的主要部分通过化学元素和化合物的流动相连接。在众多这样的循环中，生物群起了重要的作用。地球内部的物质通过火山喷发释放出来。大气与生物群和海洋之间进行化合物和元素的快速交换。相比之下，岩石、土壤和海洋的物质交换则通常缓慢一些。

生态系统中的能量流动是一个开放系统。太阳不断以光能的形式给予地球能量，而这些能量最终以热量的形式在食物网的各营养级中被使用和散失。碳被用来制造碳水化合物、脂肪和蛋白质，它们是食物能量的主要来源。这些化合物被氧化，释放出二氧化碳，这些二氧化碳可以被植物捕获，制造出有机化合物。这种化学反应是由太阳的光能驱动的。

将碳与氢和氧结合成能源需要太阳光，但对于阳光无法达及的深海生态系统而言，其从硫中获取能量。热液喷口附近的硫化氢可以被巨型管虫等生物体利用。在硫循环中，硫可以作为能量源被永续循环利用。能量可以通过硫化物的氧化和还原来释放（例如硫被氧化为亚硫酸盐，再被氧化为硫酸盐）。

虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。
虽然地球源源不断地从太阳获取能量，但其化学成分基本上是固定的，额外的元素只是偶尔由陨石添加。因为这些化学成分不像能量那样能被补充，所有依赖于这些化学物质的过程都必须能被循环利用。这些循环包括有生命的生物圈和无生命的岩石圈、大气圈和水圈。
生物地球化学循环可以与地球化学循环形成对比。尽管两者的部分过程是重叠的，地球化学循环仅涉及地壳和地下储库。

==储库 ==
化学物质有时会在一个地方保存很长时间。这种地方被称作储库，包括诸如能长期储存碳的煤炭沉积。<ref name="carbon">{{cite web|last1=Baedke|first1=Steve J.|last2=Fichter|first2=Lynn S.|title=Biogeochemical Cycles: Carbon Cycle|url=http://csmgeo.csm.jmu.edu/geollab/idls/carboncycle.htm|website=Supplimental Lecture Notes for Geol 398|publisher=James Madison University|access-date=20 November 2017|archive-date=1 December 2017|archive-url=https://web.archive.org/web/20171201043948/http://csmgeo.csm.jmu.edu/geollab/idls/carboncycle.htm|url-status=live}}</ref> 当化学物质只保留很短一段时间时，它们即被存放在交换池中。交换池的例子包括植物和动物。<ref name="carbon" />
动植物利用碳来生产碳水化合物、脂肪和蛋白质，这些可之后被用于构建它们的内部结构或获取能量。植物和动物短暂地使用它们系统中的碳，随后将其释放到空气或周围的介质中。一般来说，储库是非生物因子，交换池是生物因子。与煤炭层相比，碳在动植物体内只保存相对较短的一段时间。一种化学物质在一个地方保留的时间被称为其停留时间或周转时间（也称为更新时间或退出时间）。<ref name="carbon" />

右图展示了一个基本的单箱模型。储库包含了所考虑的物质''M''的量，按照化学、物理或生物属性的定义。源''Q''是流入储库的物质通量，汇''S''是流出储库的物质通量。预算是影响储库内物质周转的源和汇的制衡。当''Q'' = ''S''，即源与汇处于平衡状态且不随时间变化时，储库处于稳态。<ref name=Bianchi2007 />
停留时间或周转时间是物质在储库中停留的平均时间。如果储库处于稳态，其等于蓄满或排空储库所需的时间。因此，如果τ 是周转时间，那么 τ = M/S。<ref name=Bianchi2007 />描述储库物质含量变化率的方程为
::<math> \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}</math>
::<math> \frac{dM}{dt} = Q - S = Q - \frac{M}{\tau}</math>
当两个或多个储库相连通时，可以认为物质在储库之间循环，且循环流动具有可预测的模式。<ref name=Bianchi2007 />更复杂的多箱模型通常用数值方法求解。

左上图显示了海洋碳流动的简化预算。它由三个相互连通的简单箱模型组成，一个是真光层，一个是海洋内部或深海，一个是海洋沉积物。在真光层，浮游植物每年净生产量约为50Pg。大约10Pg被输送到海洋内部，其余40Pg则被呼吸作用消耗。有机碳的降解发生在颗粒（海洋雪）在海洋内部沉降的过程中。只有2Pg的碳最终到达海底，其余的8Pg在深海中被呼吸作用消耗。在沉积物中，可供降解的时间尺度增加了一个数量级，导致90%的有机碳被降解，最终只有0.2PgC yr<sup>-1</sup>被埋藏并从生物圈转移到地圈。<ref name=Middelburg2019 />
右上图显示了一个更复杂的模型，其中包含了许多相互作用的箱室。这里储库的质量代表碳储量，以Pg C为单位。碳交换通量以Pg C yr<sup>-1</sup>为单位，出现于大气和两个主要的碳汇，陆地和海洋之间。黑色的数字和箭头表示了1750年（工业革命之前）的碳库含量和交换通量的估计值。红色的箭头和对应的数字代表了2000-2009年人类活动导致的碳通量变化的年平均值。它们显示了1750年以来碳循环的变化情况。储库中的红色数字表示了自1750年至2011年，即工业革命开始以来人为碳的累积变化。<ref>{{cite journal |doi = 10.1063/1.1510279|title = Sinks for Anthropogenic Carbon|year = 2002|last1 = Sarmiento|first1 = Jorge L.|last2 = Gruber|first2 = Nicolas|journal = Physics Today|volume = 55|issue = 8|pages = 30–36|bibcode = 2002PhT....55h..30S}}</ref><ref>{{cite journal |doi = 10.13140/2.1.1081.8883|year = 2013|last1 = Chhabra|first1 = Abha|title = Carbon and Other Biogeochemical Cycles}}</ref><ref name=Kandasamy2016>{{cite journal |doi = 10.3389/fmars.2016.00259|title = Perspectives on the Terrestrial Organic Matter Transport and Burial along the Land-Deep Sea Continuum: Caveats in Our Understanding of Biogeochemical Processes and Future Needs|year = 2016|last1 = Kandasamy|first1 = Selvaraj|last2 = Nagender Nath|first2 = Bejugam|journal = Frontiers in Marine Science|volume = 3|s2cid = 30408500|doi-access = free}} [[File:CC-BY icon.svg|50px]] Material was copied from this source, which is available under a [https://creativecommons.org/licenses/by/4.0/ Creative Commons Attribution 4.0 International License] {{Webarchive|url=https://web.archive.org/web/20171016050101/https://creativecommons.org/licenses/by/4.0/ |date=2017-10-16 }}.</ref>

快速的碳循环案例如左下图所示。这一循环包括环境和生物圈中生命体之间相对短期的地球化学过程。它包括碳在大气以及陆地和海洋生态系统、泥土和海底沉积物之间的运移。快速循环包括涉及光合作用的年周期和涉及植被生长和分解的年代周期。快速碳循环对人类活动的响应将决定气候变化许多更直接的影响。

慢速循环如右上图所示，它涉及到岩石循环中的中长期地球化学过程。海洋和大气之间的交换可能需要几个世纪，而岩石的风化可能需要数百万年。海洋中的碳沉积在海底，在那里形成沉积岩并潜入地幔。造山运动使得这种地质碳回到地表。在地表，岩石被风化，碳通过脱气作用返回大气，通过河流返回海洋。其它的地质碳通过含钙离子热液的排放回到海洋。在一年中，有一千万至一亿吨的碳在这个缓慢的循环中移动。这包括火山将地质碳以二氧化碳的形式直接返还大气。然而，这还不足燃烧化石燃料排放到大气中的二氧化碳的百分之一。<ref name=Libes2015 /><ref name="Bush2020">{{cite book|doi = 10.1007/978-3-030-15424-0_3|url = https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|title = Climate Change and Renewable Energy|year = 2020|last1 = Bush|first1 = Martin J.|pages = 109–141|isbn = 978-3-030-15423-3|s2cid = 210305910|access-date = 2021-09-27|archive-date = 2021-09-27|archive-url = https://web.archive.org/web/20210927001642/https://books.google.com/books?id=h_60DwAAQBAJ&q=%22Climate+Change+and+Renewable+Energy%22+%22The+Carbon+Cycle%22chapter+%3D+The+Carbon+Cycle&pg=PA109|url-status = live}}</ref>
