Ch. 16

Question 1

stream

Answer 1

any channeled flow of water

Question 2

fluvial process

Answer 2

those that involve running water, encompass both the unchanneled downslope movement of water called overland flow. and the channeled movement of water along the valley bottom called stream flow

Question 3

valley

Answer 3

portion of the terrain on which a drainage system is clearly established

Question 4

interfluve

Answer 4

the higher land above the valley walls that separate adjacent valleys

Question 5

drainage basin or water shed

Answer 5

all the area that contributes overlain flow, stream flow, and groundwater to the stream

Question 6

fluvial erosion and deposition

Answer 6

remove sediments and transport them to another location, the movement and deposition by water creates very different landforms

Question 7

erosion by overland flow

Answer 7

fluvial erosion begins when rain starts to fall. infiltrates soil,

Question 8

erosion by stream flow

Answer 8

erodes and transports materials. volume and velocity of water has a significant effect

Question 9

transportation

Answer 9

movement of rock material

Question 10

stream load

Answer 10

material that reaches stream and is then carried. three component

Question 11

dissolved load

Answer 11

minerals that are dissolved in the water and carried in the solution

Question 12

suspended load

Answer 12

very low settling sped, particles of clay and silt. carried along in the water without ever touching the stream bed

Question 13

bedload

Answer 13

sand gravel and larger rocks fragments, jumps or bounces along with stream or the larger pieces are rolled

Question 14

deposition

Answer 14

whatever has been carried by the stream is eventually set down.

Question 15

alluvium

Answer 15

stream deposited sediment.

Question 16

stream channel patterns

Answer 16

straight-short, sinous-irrgular and gentle curvature, meandering-highly variable, braided-multiple interwoven channels

Question 17

dendritic drainage pattern

Answer 17

treelike and branching, most common

Question 18

trellis pattern

Answer 18

alternating bands of tilted hard and soft strata (bedrock), with long parallel streams linked by short rigid angle segments. ridge and valley areas

Question 19

radial pattern

Answer 19

develop around an elevated central point such as a volcano

Question 20

deranged

Answer 20

develop from an interruption of a pre existing drainage pattern

Question 21

floodplain

Answer 21

wide low lying areas around a river

Question 22

levees

Answer 22

low banks that suffice to keep the stream in its channels during normal flow

Question 23

bluff/escarpment

Answer 23

steep slopes at the outer edge of the floodplain

Question 24

alluvial fan

Answer 24

fan shaped landform that develops when a high velocity stream carries large bed loads and discharges the load into a broad flat valley floor

Question 25

delta

Answer 25

high velocity stream discharges its load in broad slower moving body of water
