"Earth's crust" Quotes from Famous Books
 ... hydraulic principles, and quite different things from geyser action, which try to explain it as you will, always runs into a volcanic groove. Yet the periodicity of a geyser's action cannot be said to be entirely due to volcanic agency. For the mere action of heat on the solids of the earth's crust, or even of heat in simple conjunction with water, according to either Mackenzie or Tyndall's theories, [Footnote: Sir G. S. Mackenzie's 'Travels in Iceland,' in 1810, p. 228. Prof. Tyndall 'On Heat,' p. 126.] even did they suffice to give a satisfactory explanation ...

... by floods, or on rafts, or in roots of large trees, or the germs of one plant or animal attached to or in the stomach of some other animal, or by the intervention (in most cases the most probable means) of other islands since sunk or destroyed. It may be remarked that when one part of the earth's crust is raised it is probably the general rule that another part sinks. Let this island go on slowly, century after century, rising foot by foot; and in the course of time we shall have instead a small mass of rock{403}, lowland and highland, moist woods and dry sandy spots, various soils, marshes, ...

... shall have good reason to suppose that, though the past of the earth is very prolonged, its future will probably be far more so. As for life—and we must think not only of human life, but of life as a planetary phenomenon—that is necessarily much more recent than the formation even of the earth's crust, the existence of water in the liquid state being necessary for life in any of its forms. And human life itself, though the extent of its past duration is seen to be greater the more deeply we study the records, is yet a relatively recent thing. The utmost, ...
— Woman and Womanhood - A Search for Principles • C. W. Saleeby
... first place, assume a general equality between elevation and subsidence during any given period, because if the elevation over any extensive continental area were not balanced by some subsidence of approximately equal amount, an unsupported hollow would be left under the earth's crust. Let us now suppose a continental area to sink, and an adjacent oceanic area to rise, it will be seen that the greater part of the land will disappear long before the new land has approached the surface of the ocean. This difficulty will not be removed by supposing ...
— Darwinism (1889) • Alfred Russel Wallace
... the globe. According to the first of these hypotheses, living beings, such as now exist, have existed from all eternity upon this earth. We tested that hypothesis by the circumstantial evidence, as I called it, which is furnished by the fossil remains contained in the earth's crust, and we found that it was obviously untenable. I then proceeded to consider the second hypothesis, which I termed the Miltonic hypothesis, not because it is of any particular consequence whether John Milton seriously entertained it or not, but because it is stated ...
