Carbon Cycle: The article's first sentence gives a brief but comprehensive overview of the main spheres of the carbon cycle. This setup allows for the author to organize the content based off the spheres. The author does a good job of having a table of contents to offer an easier way to look for information amongst this lengthy article. There are numerous links and citations throughout the work for persons that may need more clarification on concepts in the text. The author maintained a neutral tone throughout the article. There isn't any biased information or any viewpoints that seem to be under-presented or overrepresented. There are numerous wiki pages linked to the article to offer further details on jargon. Citation links work and are of pieces of credible sources that come from journals that have multiple references. Improvements to this article could be to make certain sections smaller such as the background. I felt it was a lot at once, rather than a quick overview that gave insight to other sections in the page.

Silica Cycle: The article's opening paragraph is well put together in placing silica's role in Earth's system. It mentions its overlap with other cycles such as carbon. There is a table of contents that makes the content appear more organized.It mentions the major components of the cycle, such as terrestrial, anthropogenic, and rivers, by breaking them up into smaller sections that detail their specific sources and sinks, the overall amounts they contribute, and any notable chemical reactions. All this information is cited with links to other wiki pages for any unknown scientific jargon.The contents tone is overall neutral with a few noted biases which the author references specific scientist's works and the reference cited. The author of this cycle also made a sub-section right above the references just for related cycles if any readers wanted to know more about how the silica is connected to the carbon and oxygen cycle. There are many references listed and the links work and are from credible sources that come from journals.

Selenium Cycle: The article first gives a brief overview of the cycle and its main components. The article also mentions similarities to other known cycles such as nitrogen and carbon. The content is organized into its main components in the table of contents. The content in certain sections is oddly written; for example, the first section lists the three outcomes of dissolved selenium in paragraph form. This could be done in a list form by bullet points or list the number of importance in words rather than through numerical values. The contents information could have more links to wiki pages and define some of the scientific jargon in the text. Some of the content doesn't have citations, such as the paragraph under the immobilization process, so it's difficult to tell if this is a biased viewpoint or facts from a reputable source. The references links work and are from journals that are reliable and neutral sources. The article's author could have included more references for this cycle to explain the terrestrial side since the figure on the left illustrates seleniums many pathways are in the soil on land, not only in aquatic ecosystems.
