Directions All the topographic maps used in the exercise are also gathered together in this GigaPan image (Links to an external site.) (https://viewer.gigamacro.com/view/mcmmbwGWMQrI7E88? x1=12401.50&y1=-2132.00&res1=18.16&rot1=0.00) . We recommend using the GigaPan image to answer all the lab questions, since in a few cases specific areas of the maps are highlighted/outlined in black boxes. Always remember that when you adjust the magnification of a GigaPan map, you are also altering the horizontal scale bar! If for some reason the GigaPan map collection is giving you trouble, then you may go to the individual PDFs of the USGS topo maps linked below. The lab assignment contains references to these individual topographic maps East Brownsville, Texas (https://learn.vccs.edu/courses/561798/files/147274092/download? wrap=1) (https://learn.vccs.edu/courses/561798/files/147274092/download?download_frd=1) Paw Paw, West Virginia (https://learn.vccs.edu/courses/561798/files/147274102/download?wrap=1) (https://learn.vccs.edu/courses/561798/files/147274102/download?download_frd=1) Waldron, Arkansas (https://learn.vccs.edu/courses/561798/files/147274070/download?wrap=1) (https://learn.vccs.edu/courses/561798/files/147274070/download?download_frd=1) Red Leaf, Arkansas (https://learn.vccs.edu/courses/561798/files/147274076/download?wrap=1) (https://learn.vccs.edu/courses/561798/files/147274076/download?download_frd=1) Lake Scott, Kansas (https://learn.vccs.edu/courses/561798/files/147274096/download?wrap=1) (https://learn.vccs.edu/courses/561798/files/147274096/download?download_frd=1) Ennis, Montana (https://learn.vccs.edu/courses/561798/files/147274108/download?wrap=1) (https://learn.vccs.edu/courses/561798/files/147274108/download?download_frd=1) , and adjacent Fan Mountain, Montana (https://learn.vccs.edu/courses/561798/files/147274374/download?wrap=1) (https://learn.vccs.edu/courses/561798/files/147274374/download?download_frd=1)

There is no time limit. You have up to three attempts to complete the assignment, but you must complete the entire assignment and submit it each time. The highest grade will be recorded in Grades. Grading Your assignment will be graded according to how many answers you get correct on the lab. There are 60 possible points, including two short "essay" questions and many multiple choice or fill-in-the-blank questions. Take the Quiz Again

Because the river meanders from side to side. Because politicians redraw the border frequently. Because the river avulses (changes its position) from one braided channel to another.

Less stable. Base level drop would lead to increased meandering. Less stable. Base level drop would flood the entire region. More stable. Base level drop would lead to an increase in oxbow lakes in the region. More stable. Base level drop would cause the river to incise, locking it in place on the landscape. 2 / 2 pts Question 4 Map of Paw Paw, WV (+MD): What channel type is shown here? straight meandering sinuous

(Hint: note the magnitude of the elevation contours) Weird; an old age river system it should have oxbows... I don't get it. The rejuvenation has incised the river, "entrenching" the meanders into bedrock. They are no longer moving side to side over time. This river is too young to have yet developed any oxbows. This isn't a natural river pattern, but a human-constructed river channel shape.

Which one makes up the ridges (not the valleys)? mudstone quartz-rich sandstone granite schist 0 / 2 pts Question 8 Incorrect Incorrect Map of Waldron, AR: The rings of bedrock in this region are composed of alternating layers of mudstone and quartz-rich sandstone.
