Could you answer all of the following questions?
activity 4.4b number 1-4 and 7a-e in the book : applications and investigations in earth space science 8th edition
refer to the angelica, new york, topographic map (figure 4.8) on page 74 to complete the following.
1. draw an arrow on the map to indicate the direction that the main river, the genesee, is flowing. (hint: use the
elevations of the two bench marks [bm] next to the river near the top and bottom of the map to determine your
answer.)
2. use the bm elevations from question 1 to calculate the approximate gradient of the genesee river. (hint: see
question 7 in activity 4.4a.)
gradient: feet per mile
3. use figure 4.9 to draw a profile along line a–a’. use only guide contour lines. (note: figure 3.13 on page 60 contains a detailed explanation of how to construct topographic profiles.)
4. approximately how many feet is the genesee river above ultimate base level? feet
7. use the fractional scales on the angelica topographic map and the portage, montana, map (page 72) to answer
the following.
a. what is the fractional scale for the angelica map?
b. how does this compare to the fractional scale for the portage, montana, map?
c. what distance (in miles) does 1 inch represent on each map?
angelica, new york, map: miles
portage, montana, map: miles
d. does the angelica map cover more or less area than the portage map?
e. explain why the angelica map lacks numbered sections that we associate with the public land survey system.
