  2. Marine biogeochemical cycles - Wikipedia

    en.wikipedia.org/wiki/Marine_biogeochemical_cycles

    Water carried into the mantle eventually returns to the surface in eruptions at mid-ocean ridges and hotspots. [131]: 646 Estimates of the amount of water in the mantle range from 1 ⁄ 4 to 4 times the water in the ocean. [131]: 630–634 The deep carbon cycle is the movement of carbon through the Earth's mantle and core.

    The possibility remained that liquid ethane and methane might be found on Titan's polar regions, where they were expected to be abundant and stable. [7] In Titan's south polar region, an enigmatic dark feature named Ontario Lacus was the first suspected lake identified, possibly created by clouds that are observed to cluster in the area. [ 8 ]

    en.wikipedia.org/wiki/Chemosynthesis

    Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...

  7. Azeotropic distillation - Wikipedia

    en.wikipedia.org/wiki/Azeotropic_distillation

    The addition of a material separation agent, such as benzene to an ethanol/water mixture, changes the molecular interactions and eliminates the azeotrope. Added in the liquid phase, the new component can alter the activity coefficient of various compounds in different ways thus altering a mixture's relative volatility.

  8. Ethane - Wikipedia

    en.wikipedia.org/wiki/Ethane

    Although ethane is a greenhouse gas, it is much less abundant than methane, has a lifetime of only a few months compared to over a decade, [30] and is also less efficient at absorbing radiation relative to mass. In fact, ethane's global warming potential largely results from its conversion in the atmosphere to methane. [31]

    Ocean: a major body of salty water that, in totality, covers about 71% of the Earth's surface. Oxbow lake: a U-shaped lake formed when a wide meander from the mainstem of a river is cut off to create a lake. Phytotelma: a small, discrete body of water held by some plants. Plunge pool: a depression at the base of a waterfall. Pool
