Continental Shelf Surface

Famous quotes containing the words shelf and/or surface:

    The shelf life of the modern hardback writer is somewhere between the milk and the yoghurt.
    John Mortimer (b. 1923)

    The surface of the earth is soft and impressible by the feet of men; and so with the paths which the mind travels. How worn and dusty, then, must be the highways of the world, how deep the ruts of tradition and conformity!
    Henry David Thoreau (1817–1862)
