Cloud Cover

Cloud cover (also known as cloudiness, cloudage or cloud amount) refers to the fraction of the sky obscured by clouds when observed from a particular location. A planet surrounded by cloud cover would become an arctic wasteland while a planet without cloud cover would become a waterless desert where even reptiles are incapable of surviving and thriving (due to an excessive amount of greenhouse gasses and solar radiation that would develop).

Famous quotes containing the words cloud and/or cover:

    O months of blossoming, months of transfigurations,
    May without cloud and June stabbed to the heart,
    I shall not ever forget the lilacs or the roses
    Nor those the spring has kept folded away apart.
    Louis Aragon (1897–1982)

    You may call a jay a bird. Well, so he is, in a measure—because he’s got feathers on him, and don’t belong to no church, perhaps; but otherwise he is just as much a human as you be. And I’ll tell you for why. A jay’s gifts and instincts, and feelings, and interests, cover the whole ground. A jay hasn’t got any more principle than a Congressman.
    Mark Twain [Samuel Langhorne Clemens] (1835–1910)
