QUIZ Time! GG1113 Not Graded but Scored in Class Rules:- Two groups – Alluvial fan group & Delta group: you can discuss among group members if required. Approx. 30 seconds per question. 1 score for every right answer. No negative scores for wrong answers. I keep the score. Unanswered questions and wrongly answered questions passes to next group – 0.5 score for correctly answering passed questions. 1 discretionary bonus point to be awarded by me to the total for group participation and energy! Choose the correct option The land drained by a network of streams is called a: 1) Delta 2) Canyon 3) Watershed 4) Meander Choose the correct option Erosion occurring via intense scouring in an upstream direction opposite to flow direction in the uppermost part of a stream/channel is called: 1) Headwater erosion 2) Undercutting 3) Downcutting 4) Debris flow Choose the correct option Smaller streams joining the main channel in the upper reaches of a stream are called: 1) distributaries 2) tributaries 3) avalanche 4) slump Choose the correct option The drainage pattern produced by rivers when flowing over uniform substrate that look like branches connecting to the trunk of a tree is known as: 1) radial 2) dendritic 3) trellis 4) parallel What is the difference between: Permanent streams and ephemeral streams State True or False Discharge is the volume of water flowing through a channel at a specific point in time. 1) True 2) False Choose the correct option The drainage is calculated as stream width x stream depth x ______ 1) volume 2) density 3) velocity 4) specific gravity Choose the correct option The drainage pattern produced by channels when flowing over alternating hard and soft rocks and joining the main channel at approximately right angles is known as: 1) dendritic 2) radial 3) trellis 4) parallel Choose the correct option The mode of transport when a sediment move through a channel in the form of alternate jumping it is called: 1) skipping 2) jumping 3) saltation 4) eddy Choose the correct option The maximum particle size that can be carried by a stream is called its’: 1) competence 2) capacity 3) discharge 4) intensity Choose the correct option The total sediments that can be carried by a stream is called its’: 1) competence 2) capacity 3) discharge 4) intensity Choose the correct option Near the headwater source of the stream, the gradient is ______, discharge is ____, sediments are ____, and the channel is ______ and rocky. 1) Steep, high, coarse, straight 2) Steep, low, fine, meandering 3) Steep, low, coarse, straight 4) Steep, high, fine, meandering State True or False A slower flow has lower competence. 1) True 2) False Choose the correct option The competence of a stream depends on: 1) flow speed and sediment sorting 2) sediment sorting and discharge 3) discharge and flow speed 4) flow speed and viscosity Choose the correct option The Nile delta is an example of __________ delta: 1) Bird’s foot 2) arcuate 3) abandoned 4) estuarine Choose the correct option The capacity of a stream depends on: 1) flow speed and sediment sorting 2) sediment sorting and discharge 3) discharge and competence 4) flow speed and viscosity Choose the correct option The drainage pattern produced by rivers when flowing over pre- existing fractures and join each other at right angles is known as: 1) rectangular 2) radial 3) trellis 4) parallel State True or False A large river has more capacity than a smaller river. 1) True 2) False Choose the correct option The lowest elevation that a stream channel’s surface can reach at a locality is called the ___________ of the stream. 1) channel bed 2) base level 3) ceiling 4) floor Choose the correct option Toward the mouth of a stream, the gradient is _________, discharge is ________, sediment grain sizes are _______, and channels are ________. 1) Flat, high, coarse, straight 2) Flat, low, fine, meandering 3) Flat, low, coarse, straight 4) Flat, high, fine, meandering Choose the correct option Deposit of sediments due a change in gradient at the foot of a mountain is called 1) Delta 2) Levee 3) Point bar 4) Alluvial fan Choose the correct option Streams forced to flow around sediment obstructions causing converging and diverging patterns of stream flow is called: 1) Dendritic drainage 2) Braided stream 3) Trellis drainage 4) Radial drainage Choose the correct option Sand deposits in the form of ridges parallel to the channel are called: 1) Point bars 2) Flood plain 3) levee 4) crevasse Choose the correct option Rivers erode the ________ bank and deposit point bars along the _______ banks of a meandering channel 1) Outer ; inner 2) Left ; right 3) Right ; left 4) Inner ; outer Choose the correct option A natural process where a river's flow is diverted from its established channel into a new course at a lower elevation is called: 1) Channel avulsion 2) Stream piracy 3) Channel capture 4) Ephemeral stream Choose the correct option Sediments deposited in a standing body of water is called a: 1) Alluvial fan 2) delta 3) Point bar 4) Ox-bow lake Choose the correct option Channels diverging and flowing away from a main channel are called: 1) distributaries 2) tributaries 3) avalanche 4) slump Choose the correct option The Mississippi delta is an example of __________ delta: 1) Bird’s foot 2) arcuate 3) abandoned 4) estuarine Choose the correct option The diversion of flow due to headward erosion when a stream intersects another stream diverting the water from the latter stream into its own channel is called: 1) Channel avulsion 2) Stream piracy 3) Channel meander 4) Ephemeral stream Choose the correct option When a meandering channel starts downcutting due to a fall in base level or a tectonic uplift it is called: 1) Channel avulsion 2) Stream piracy 3) Channel meander 4) Stream rejuvenation
