With these geology questions if someone can please help thank you! With answers Which has greater competence? a a small, steep mountain stream 75. b. a broad, slow-flowing river Which has greater capacity? out 76. a smal, steep mountain stream b. a broad, slow-flowing river evel The stream gradient of most rivers a is greater near the source than near the mouth b. 77· is greater near the mouth than ncar the source ped does not change significantly as the river flos c downstream d is greater for a meandering stream than for any other The distinction between a valley and a canyon is a nonexistent, the two terms are synonymous type 78. that the sides ofa canyon are steeper than those ofa valley b c that the sides of a valley are steeper than those of a canyon d. that valleys are often cut by streams; canyons are eroded out by the wind Braided streams a consist of a series of intertwined channels that are 79, overloaded with sediment b. have flowing water either episodically or during a portion of the year c. have a channel that is highly sinuous (curvy) d. are antecedent with respect to geologic structures 80. Within a meander, where is sediment most likely to be deposited? a on the outer bank (cut bank) of the meander b. on the inner bank (point bar) of the meander c uniformly to either side of the meander 1. Silt-sized particles transported hundreds of km or more and deposited in sometimes thick layers during the ice ges are b. loess c outwash 2 Sediments deposited directly by glaciers as they melt are characterized by a uniformly coarse grain size b. uniformly fine grain size c. an absence of sorting d. graded beddingExplanation / Answer
