Most of the mountains in southern Nevada are composed of carbonate rocks. We can perhaps conclude from this discussion that high relief, or more accurately steep slopes, promote preservation of rock fragments, which appear to be the most sensitive indicators of weathering conditions. This comparison can be made by plotting both the calculated relative clast abundance and the measured relative clast abundance on the same cumulative-curve diagram or histogram, as illustrated in Fig. 7.17.

Deposition - Sediment is deposited when the energy of the transporting medium becomes too low to continue the transport process. In other words, if the velocity of the transporting medium becomes to low to transport sediment, the sediment will fall out and become deposited , source: Sedimentary Geology and Mineral Deposits of the Canadian Cordillera, 1973, GAC, Programme and abstracts, Cordilleran Section : 24 pages with illustrations. download online Sedimentary Geology and Mineral Deposits of the Canadian Cordillera, 1973, GAC, Programme and abstracts, Cordilleran Section : 24 pages with illustrations. online.

Therefore, many investigators resort to visual estimates of grain roundness aided by the use of visual estimation charts. Several such charts have been proposed; however, the roundness scale of Powers (1953; Fig. 2.12) appears to be most widely used. Although visual estimates of grain roundness can be done quite rapidly, reproducibility of results, even by the same operator, can be quite low , cited: The Geology of Sirt Basin, Volume Volume I The Geology of Sirt Basin, Volume Volume I book.

As a basis for understanding this concept, and to address the content in the other three strands, students should develop their own questions and perform investigations.
