The Carbon Cycle word list, defined
- CARBON /ˈkɑːrbən/ · noun
- A nonmetallic chemical element (symbol C, atomic number 6) that occurs in all living organisms and exists in several forms, including diamond and graphite. It is also used more broadly to refer to carbon dioxide emissions, especially in the context of climate change. Related: element, soot, charcoal, graphite.
- DIOXIDE /daɪˈɒksaɪd/ · noun
- An oxide containing two atoms of oxygen in each molecule, especially the compound carbon dioxide (CO₂). The term most commonly refers to specific named compounds such as carbon dioxide, sulfur dioxide, and titanium dioxide.
- RESPIRATION /rˌɛspəˈreɪʃən/ · noun
- The process of breathing, especially the repeated exchange of gases between an organism and the environment. In biology, the term can also refer more broadly to the uptake of oxygen and release of carbon dioxide by living tissues. Related: breathing, breath, ventilation, gas exchange.
- PHOTOSYNTHESIS /ˌfoʊtoʊˈsɪnθəsɪs/ · noun
- The biological process by which plants, algae, and some bacteria use light energy to convert carbon dioxide and water into glucose and other organic compounds, releasing oxygen as a by-product.
- DECOMPOSITION /ˌdiːkɒmpəˈzɪʃən/ (UK), /ˌdiːkɑːmpəˈzɪʃən/ (US) · noun
- The process by which something breaks down or decays into its component parts, whether through biological decay, chemical change, or analytical separation. Related: decay, rot, putrefaction, breakdown.
- COMBUSTION /kəmˈbʌstʃən/ · noun
- The process of burning, in which a substance combines rapidly with oxygen and releases heat and light. More broadly, any violent chemical change or turmoil, though this figurative sense is rare today. Related: burning, ignition, oxidation, fire.
- FOSSIL /ˈfɒs.əl/ (UK), /ˈfɑː.səl/ (US) · noun
- The remains or impression of a prehistoric organism preserved in rock, or, informally, an old-fashioned or outdated person, idea, or practice. Related: relic, remnant, remains, trace.
- FUELS /ˈfjuːəlz/ · noun
- Fuels is the plural of fuel: substances such as coal, oil, natural gas, or wood that are burned or otherwise consumed to produce heat, power, or energy. Related: energy sources, propellants, combustibles, petrol.
- ATMOSPHERE /ˈætməsfɪr/ · noun
- The envelope of gases surrounding the Earth or another planet; also the air or climate in a particular place, or the prevailing mood or feeling of an environment. Related: ambiance, air, mood, environment.
- OCEAN /ˈoʊʃən/ · noun
- A very large expanse of seawater covering much of the Earth, forming interconnected bodies of water conventionally identified as the Pacific, Atlantic, Indian, Arctic, and Southern oceans. The word can also refer figuratively to a vast, boundless quantity or expanse of something. Related: sea, main, deep, waters.
- ABSORPTION /əbˈzɔːrpʃən/ · noun
- The process by which one thing takes in or soaks up another, whether a liquid, gas, light, or information; also the state of being completely engrossed in something. Related: assimilation, uptake, soaking up, engrossment.
- RELEASE /rɪˈliːs/ · noun and verb
- As a verb, to allow someone or something to leave, become free, or be published or made available. As a noun, an act of freeing, authorizing, issuing, or making something publicly available. Related: free, liberate, discharge, publish.
