Question

Hello! I would love if someone could help verify the profile graph below with the correct points! I just want to make sure I didn't identify the hills, slops, and creeks in the wrong spots! Thank you!

I don't know what's needed for the contour map (1.9a) but if you can label that as well that would be amazing! Thank you!

Answer 1

This is quite simple, you just have to take a paper and have to mark all the points where it is cutting the topography. Then that points between A-A' you have to mark in the below diagram and according to the elevation (contour value) we have to mark each point.

Here the contours show an alternative dome and basin structure. There are two domes North Dome and Half Dome. This we tell as dome because from the dome at either side the contour value decreases. Within them, we are getting a basin, because on either side we are getting an increase in contour vale. The deepest point of the basin is 4000m, on either side of it the contour value increases.
