气态和沉积生物地球化学周期之间的差异

Thekey difference在气态和沉积生物地球化学周期之间main reservoir of the element. In gaseous biogeochemical cycles,the main reservoir of the element is the air or ocean.But, the main reservoir of the element is the Earth crust in sedimentary biogeochemical cycles.

Biogeochemical cycles are pathways by which substances mainly circulate through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) parts of Earth. These cycles explain the movement of a particular element via living and nonliving matter in anecosystem。有几个自然循环，包括nitrogen cycle,carbon cycle, water cycle,phosphorus cycle, and sulfur cycle. These cycles are extremely important for the existence of life and transforming energy and mater into usable forms to support ecosystem functioning.

Each cycle shows a balance in cycling between different compartments. However, human activities have greatly affected these natural cycles, creating altered and accelerated cycles that can influence the climate and pose a threat to biodiversity, food security, human health, and water quality, etc. Generally, biogeochemical cycles can be categorized into two main types as gaseous and sedimentary.

什么是气态生物地球化学周期？

Gaseous biogeochemical cycles circulate through the atmosphere and hydrosphere. Therefore, the main reservoirs of gaseous biogeochemical cycles are air and ocean. Nitrogen, oxygen, carbon, and water cycles are some of the gaseous biogeochemical cycles. Especially in the nitrogen cycle, the major reservoir is the atmosphere. In the atmosphere, more than 78% is occupied by nitrogen gas (N₂）。此外，CO的主要水库₂和o₂is also the atmosphere.

Atmospheric gases are absorbed by plants and aerobic organisms. Plants fix carbon dioxide and produce carbohydrates. We breathe air containing oxygen. In addition, gaseous cycles take place quickly than sedimentary cycles.

什么是沉积物地球化学周期？

Sedimentary biogeochemical cycles are the cycles in which the main reservoir is the soil and sedimentary rocks. Therefore, the elements of sedimentary biogeochemical cycles mainly circulate through the land to water to sediments. Basically, these cycles have a solution phase and rock phase.

From the Earth’s crust, minerals are released by the weathering process. Then they become salts in water. These elements circulate through a series of organisms and finally come to the sea. Some salts deposit in rock while some salts settle in sediments. Most importantly, these elements do not move through the air. Iron, calcium, phosphorus, and other more earthbound elements are sedimentary biogeochemical cycles.

气态和沉积生物地球化学周期之间有什么相似之处？

• Gaseous and sedimentary cycles are two main categories of biogeochemical cycles.
• 他们描绘了元素通过地球不同隔室的运动。
• They are natural cycles.
• However, human activities accelerate and alter both types of cycles.

What is the Difference Between Gaseous and Sedimentary Biogeochemical Cycles?

气态循环是元素的主要储层是空气或水。同时，沉积周期是循环，其中该元素的主要储层是地壳。因此，这是气态和沉积生物地球化学周期之间的关键区别。例如，氮，氧气，碳和水周期是气态周期，而铁，钙，磷和其他更多地球元素循环是沉积周期。

Moreover, gaseous biogeochemical cycles are fast, while the sedimentary biogeochemical cycles are slow. Therefore, this is another difference between gaseous and sedimentary biogeochemical cycles.

总结——气体沉积生物地球化学Cy vscles

气态生物地球化学循环主要在大气中移动。因此，他们的主要水库是空气或海洋。相反，沉积物地球化学循环穿过土壤或地壳，因此其主要储层是岩石圈。因此，这是气态和沉积生物地球化学周期之间的关键区别。此外，气态循环发生得非常快，而沉积周期非常慢。例如，氮，氧气，碳和水周期是气态周期，而铁，钙，磷和其他更多地球元素循环是沉积周期。
