"Denudation" Quotes from Famous Books
 ... so long in the history of the earth. All the time, then, that the forces of the atmosphere are wearing down the surface of the earth to the sea level the sea is rising and its waves are producing a plain of marine denudation which rises slowly to meet the peneplain which is produced by degradation. In the beginning of this cycle, where the forces of degradation have their own way, coarse material may be brought down by torrents from the mountains, and ...

... of railway locomotion. The subject was always a favourite one with Mr. Stephenson, and, encouraged by the king, he proceeded to describe to him the geological structure of Belgium, the original formation of coal, its subsequent elevation by volcanic forces, and the vast amount of denudation. In describing the coal-beds he used his hat as a sort of model to illustrate his meaning; and the eyes of the king were fixed upon it as he proceeded with his interesting description. The conversation then passed to the rise and progress of trade and manufactures,—Mr. ...

... those days at the canon of the geology of my native hills amid the Catskills, which show the effects of denudation as much older than that shown here as this is older than the washout in the road by this morning's shower! The old red sandstone in which I hoed corn as a farm-boy dates back to Middle Palaeozoic time, ...

... authority. Commence by liberally granting the requirements and wishes of the public, and prepare yourselves to defend, even by force, all that violent, factious, and extravagant systems would assail. In the state of uncertainty, embarrassment, and denudation in which you have placed yourselves, you have no strength, I can feel, I can see. Get out, then, of this state; put fresh energy into your concessions, into your plans; in a word, take up a decided attitude, for ...

... against the project, so steep was the comblike summit on either side, so heavy and tortuous the outcropping rock that served as the bony structure of the great mountain mass. True, the river pierced it, the denudation of solid sandstone cliffs, a thousand feet in height, betokening the untiring energy of the eroding currents of centuries agone. This agency, however, man might not summon to his aid, being "the act of God," to use the pious language of the express companies to ...

... surface since the beginning of geological time; the resulting knowledge in no way involving any assumption as to the duration of the period comprising the denudative actions. This idea has been elaborated in various publications since then, both by myself and by others. "Denudation," while including a survey of the subject generally, is mainly a popular account of this method and its results. It closes with a reference to the fascinating problems presented by the inner nature of sedimentation: a branch of science ...

... 1871.—We went along a ridge of land overhanging a fine valley of denudation, with well-cultivated hills in the distance (N.), where Hassani's feat of bloodshed was performed. There are many villages on the ridge, some rather tumbledown ones, which always indicate some misrule. Our march was about seven miles. A headman who went with us plagued another chief ...

... That such a denudation actually occurred is of course within the bounds of geological possibility, if we take the precaution to date the incident far enough back, to remote and prehistoric days. There is little credence to be attached to the local traditions, which affirm that fishermen on a calm, clear day, have ...

... this wealth, and put it in their pockets, there is but one-fourth left to divide among the nine hundred and ninety, and they are therefore poor and miserable. Within certain limits accumulation in one place represents denudation elsewhere. ...

... instance I was suddenly and stunningly confronted by a yellow gulf of cone-shaped and fan-shaped ridges, all bare crinkly clay, of gold, of amber, of pink, of bronze, of cream, all tapering down to round-knobbed lower ridges, bleak and barren, yet wonderfully beautiful in their stark purity of denudation; until at last far down between two widely separated hills shone, dim and blue and ghastly, with shining white streaks like silver streams—the Valley of Death. Then beyond it climbed the league-long red slope, merging into the iron-buttressed base of the ...

... and boulders; and elsewhere, after decomposing the feldspar into a white clay, carry away this and the accompanying quartz and mica, and deposit them in separate beds, fluviatile and marine. When the exposed land consists of several unlike kinds of sedimentary strata, or igneous rocks, or both, denudation produces changes proportionably more heterogeneous. The formations being disintegrable in different degrees, there follows an increased irregularity of surface. The areas drained by different rivers being differently constituted, these rivers carry down to the ...

... on which we now entered, it presents only two of these—the lower quartz-rock, and the underlying red sandstone; but wherever any of its members appear, they present unique features—marks of enormous denudation, and a bold style of landscape altogether its own; and, in now entering upon it for the first time, I was much impressed by its extraordinary character. Loch Maree, one of the wildest of our Highland lakes, and at this time scarce at all known to the tourist, owes to it all ...

... Sierra Madres were formerly covered with thick forests, and in some regions are still so covered. But they have been denuded in certain regions of their timber, principally for fuel, as native coal has been unknown until recently, and is difficult of transport. This denudation has had an undoubted effect upon the rainfall, and has served to change the climatic conditions in these regions. In other upland regions, however, the splendid and extensive forests of oak and pine form marked features of the landscape, and are of ...

... called accidental, but the term is not strictly applicable; for the shape of each depends on a long sequence of events, all obeying natural laws; on the nature of the rock, on the lines of deposition or cleavage, on the form of the mountain, which depends on its upheaval and subsequent denudation, and, lastly, on the storm or earthquake which throws ...
