science question..?

Question

can someone help me answer this for my lab:

2.The pit in the top of the mountain on the model must be shown on a flat map as a depression and not as a hilltop. What method might be used to show that the contours in the pit really do suggest a depression?

3.A view from directly above shows that when a contour line crosses a gulley on a mountain, it changes direction suddenly. The contour line is somewhat V-shaped. Does the “V” point toward the top of the mountain or toward the valley?

This is for my science lab. Please help me!

Answer 1

Most of the contour maps I use intermittentlly break lines with elevation numbers. The highest points of peaks are also marked. In your case, Just marking the highest point with a black X, for example, near one of the contour lip lines would do the trick.

Answer 2

2. use hachures pointing downhill.

3. Contour lines in a gully always point uphill, and on a ridge they point downhill. Therefore in your case the contour line would point toward the mountain.

Its always best to do your own homework; get a topo map and study it. See how the contour lines show valleys, ridges, mountains, and depressions. Remember that countour lines join points of equal elevation, therefore any one contour line is at the same elevation along its entire length.
