The Carbon Cycle :: Biological and Geological
The above diagram shows the "BIOLOGICAL" carbon cycle - carbon cycling through vegetation, herbivores, carnivores/omnivores, soil and in fossil fuel burning. There is another part of the carbon cycle - the "GEOLOGICAL" carbon cycle (or carbon-rock cycle) as shown in the diagram below (modified from National Aeronautics and Space Administration).

Carbon, with all its qualities, also has its shortfalls. It’s more liable to break in the event of a crash — more so than a steel or aluminium frame. A repaired headtube-downtube junction.

Sulfur cycle - Wikipedia
These are often termed as follows: Assimilative sulfate reduction (see also sulfur assimilation) in which sulfate (SO 4 2−) is reduced by plants, fungi and various prokaryotes.The oxidation states of sulfur are +6 in sulfate and –2 in R–SH. Desulfurization in which organic molecules containing sulfur can be desulfurized, producing hydrogen sulfide gas (H 2 S, oxidation state = –2).

Introduction to Carbon and Carbon Stores | Geography | …
2020/7/31· Carbon cycles, like water cycles, should be thought of as a system. There are inputs, stores, fluxes/flows and outputs that transfer carbon from one environment to another and cause stores to be depleted, or accumulate. Carbon stores (reservoirs): loion The
Phosphorus Cycle - an overview | ScienceDirect Topics
Y. Liu, J. Chen, in Encyclopedia of Ecology, 2008Organic Cycles Imposed on the inorganic cycle are two organic cycles which move phosphorus through living organisms as part of the food chain. These are a land-based phosphorus cycle which transfers it from soil to plants, to animals, and back to soil again; and a water-based organic cycle which circulates it among the creatures living in rivers
Sedimentary Rocks | National Geographic Society
2019/10/22· Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and …
Water cycle | National Oceanic and Atmospheric …
The water cycle on Earth Water is essential to life on Earth.In its three phases (solid, liquid, and gas), water ties together the major parts of the Earth’s climate system — air, clouds, the ocean, lakes, vegetation, snowpack, and glaciers offsite link. The water cycle
Natural History-Natural Cycles - Flathead Watershed
Carbon Cycle One of the most important cycles on earth, the carbon cycle is the process through which the organisms of the biosphere recycle and reuse carbon. Carbon moves through four interconnected reservoirs: the atmosphere, the terrestrial biosphere (including non-living organic materials and freshwater systems), the oceans, and sediments (including fossil fuels).

Cycles of Matter: The Nitrogen Cycle and the Carbon …
If carbon from the atmosphere does not enter a terrestrial (or land) plant by photosynthesis, it can dissolve in the ocean. Here it can be taken up by marine plants through photosynthesis - just
What Is the Hydrologic Cycle? - dummies
The hydrologic cycle involves water moving from the surface (most importantly the oceans) to the atmosphere, across the land, and everywhere in between. Environmental scientists know that the hydrologic cycle includes various processes that change water from solid to liquid to gas form and transport it to every corner of earth’s surface (and below). In […]

The cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange. Jan. 28, 2020 — An international study shows that the rapid increase in land use in the
The Rock Cycle
If we examine the rock cycle in terms of plate tectonics, as depicted in the figure above, we see that igneous rocks form on the sea floor as spreading ridges. As the rocks cool, and more magma is introduced from below, the plate is forced away from the spreading ridge, and acquires a sediment cover.
Carbon Cycle and Atmospheric CO2 | Earth 530: The …
Atmospheric carbon dioxide The carbon cycle is of interest to understanding climate because it includes two of the most important greenhouse gases: carbon dioxide (CO 2) and methane (CH 4).Most atmospheric carbon is in the form of CO 2, while CH 4 is present only in trace concentrations. is present only in trace concentrations.
