. Which of the following depends on a region the amount and distribution of precipitation, the nature of storms, and typical seasonal variations? a. weather b. climate ID: B 's average temperature and typical temperature range as well as c. weather forecast d. elimate change 85. Ephemeral streams, as opposed to permanent streams, a. are subject to erosion of sedimen. b. contain water only during rainfall. c. can be fed by large drainage basins. d. occur only in tropical regions. 86. Braided streams a. b. c. d. consist of a series of intertwined channels that are have flowing water either episodically or during only a have a channel that is highly sinuous (curvy). are those that divert flow episodically or during only a portion of the year overloaded with sediment from streams they have intersected through stream erosion 87. Why do meandering rivers meander (move) across their floodplain? amounts of sediments that choke the rivers create poim bars that are easily b. They carry very small amounts of sediment and thus are not slowed down as a result of c. They are curved, which causes erosion on one side of the curve and deposition on the d. Sediment is constantly being deposited on the river bottom, which causes the river to eroded away by additional flow of the rivers friction between the sediment and the river bottom other side of the curve, thus moving the river in the direction of erosion overflow its banks and create a new channel. 88. You are hiking in your favorite forest when you encounter a surface that appears to have very fine directional scratches in it. What are these features? a. glacial till b. c. striations d. scour marks 89. In uniform sediments with a relatively constant and gentle sope at the surface. network is expected. a. dendritic b. radial d. trellis c. d. increase in the sediment load increase in flood potential -90. If a dam is built on a river, what effects might be felt downstream? a. increase in the fish population b. decrease in sediment supply Greenhouse gases are those that a. exist in abundance in Earth's atmosphere. b. absorb energy that is reradiated from Earth's surface. c. occupy the ozone layer d. cause seasonal variations. 91. 92. Valleys carved by glaciers tend to be shaped like the letterwhereas valleys carved by water tend c. to be shaped like the letter V: b.Explanation / Answer
84. Climate change depends on a region's average temperature and typical temperature range as well as the amount and distribution of precipitaion, the nature of storms, and typical seasonal variation.
85. Ephemeral streams, as opposed to permanent streams contain water during rainfall.
86. Braided stream consist of a series of intertwined channels that are overloaded with sediments.
87. Option C is correct that they are curved, which causes erosion on one side of the curve and deposition on the other side of the curve, this moving the river in the direction of river.
88. A surface that appears to have very fine directional scratches in it this features is called scour marks.
89. In uniform sediment with a relatively constant and gentle slop in the surface, a dendritic drainage is expected.
90. If a dam is built on a river, both decrease in sediment supply and increase in Flood potential are right but more accurate is decrease in sediment supply.
91. Greenhouse gases are those that absorb energy that is reradiated from earth's surface.
