Question

How gravel is moved by streamsA) dissolved load B) suspended load C) bed load The drop in stream elevation per unit distance. A) slope B) dip C) gradient Overland nonpoint source erosion. A) rille erosion B) gully erosion C) sheet erosion Erosion by raindrops A) swoosh erosion B) splot erosion C) splash erosion D) pit erosion Easiest clast size to erode. A) clay B) sit C)sand The reason for braids. A) variable discharge B) too much sediment C) both of these Meanders have this shape. A) straight B) U-shaped C) serpentine D) V shaped The ultimate base level of streams. A) center of Earth B) poles C) sea level The effect of meanders. A) vertical erosion B) levee formation C) lateral erosion Multiple river bars. A) meanders B) oxbows C) braids To stabilize mass wasting, the first thing to do is to: A) run B) hose the area down C) dewater Can be caused by saturating a slope with water A) faulting B) jointing C) mass wasting Big heavy clasts difficult to erode·A) sand B) slate C) gravel D) siltite A cut-off meander filled with water A) short cut B) side stream C) oxbow lake Stream pattern over homogeneous geology. A) trellis B) rectangular C) dendritic D) fractal The cross-sectional area of a stream multiplied by its average velocity. A) flow B) floodstage C) discharge The big factor in all types of mass wasting. A) slope B) overloads C) water D) vegetation. Small channel caused by erosion. A) river B) divide C) gully D) mill Clay and silt carried by a stream. A) dissolved load B) bed load C) suspended load Result of polarity of water molecule.A) abrasion B) Sticky clasts difficult to erode. A) gravel B) sand C) dlay D) silt Rock anchors, dewatering and cutting slope can lead to this. A) earthquakes B) floods C) slope stability A river normally flows within these, but they break during floods. A) beaches 8) dams C) levees Example of a tide-dominated delta. A) Nile delta B) Mississippi delta C) Chesapeake Bay Stream pattern on a volcano. A) dendritic B) fractal C) radial D) rectangular The dendritic pattern. A) rectangular B) trellis C) fractal D) radial This accumulates at base of cliffs due to rockfalls. A] sandstone B) loess C) talus The boundary between drainage basins. A) ridge B) range C) divide This type of mass wasting is responsible for most property damage. A) landslides B) mudflows C creep Example of a river dominated delta. A) Bangledesh delta B) Nile delta C) Mississippi delta Regrading is an example of this type of mitigation. A) hydrological B) mechanical C) geometric Can be caused by cutting down slope vegetation A) faulting B) jointing C) mass wasting lons in a stream. A) bed load B) suspended load C) dissolved load Almost all mass wasting is triggered by A) humans B) monkeys C) water D) earthquakes Transforn faults on the ocean floor common offset these. A) veins B) roads C) train tracks D) midoceanic A divergent plate boundary A) convergent B) transform C) subducting D) constructive An ancient floodplain above the valley floor. A) oxbow ridge B) high island bar C) river terrace Mechanical scraping by streams A) dissolution B) hydraulic action C) abrasion hydraulic action C) dissolution
