1. A)900
C)1500
D)1000
2.contour interval is 100 ft
3. The difference is 0 because they’re both 900 ft high
4.the difference in elevation is 500 because C is 1500 and D is 1000 so that’s 500 ft higher
5.fish creek flows west I think, because all rivers have to end up in a drainage basin or sea, and the map gives us a hint with the compass
6.point x is 1600 because the interval is 100, the interval is the amount of distance between the lines
7.I’m not sure, I think coast? Or flat land
8.the shorter the lines to each other is the steeper it is
