• Define carbonation | Dictionary and Thesaurus

    Carbonation can occur as a result of natural processes: when yeast ferments dissolved sugars sealed in a pressuretolerant bottle or keg; when underground volcanic carbon dioxide carbonates well water; or when rainwater passes through limestone into a cave and forms a stalactite. Or it can be done artificially by dissolving carbon dioxide under ...

    Since calcium bicarbonate is soluble in water, the limestone effectively gets weathered when carbonation occurs. The role of weathering is to weaken cliffs. This weakening speeds up the rates of erosion. Another subaerial process is mass movement. A mass movement refers to the movement of material downslope under the influence of gravity.

  • What Happens in the Alveoli? |

    The exchange of carbon dioxide and oxygen occurs in the alveoli of the lungs. Oxygen is taken into the body through the process of inhalation while carbon dioxide is eliminated through exhalation. The human respiratory system mainly functions to acquire essential oxygen from the outside air and to remove carbon dioxide from the body, which is a waste metabolic product of the cells.
