what is a cross section on a contour map?? please science?

Answer 1

Actually, cross sections are on geologic maps, not contour maps. I guess you could do a cross section on a contour map (in fact, I have done them), but all it would show is the relief (hills and valleys). A cross section shows the way the geologic formations (faults, folds, strata, intrusions, etc.) look in the subsurface.

Answer 2

A contour cross section is done usually on Excel or graph paper. Decide where your line is. Knowing that a contour line denotes a rise or fall of 100 metres or feet, then you can produce an x,y graph of x-x(length along cross section) distance and terrain height.

You can then add peaks, water depth, depressions and maybe add the datum height or water level if applicable.

Connecting the points, or producing a graph in Excel will then produce an approximation of the contours along that line.

Is this question a joke? Ok well if not...then: "Why do whites keep ridiculing us Indians?" I don't think it's a race issue at all. Well personally I would not have done it, but since it is over, there is no use lamenting what has already happened... What's done is done. I think the friendship can perhaps be saved, if that's what you want... but maybe you should just give it some time for everything settle down so to speak? Also, if she was really laughing, well she is not a professional art student or a respectful friend, so I would "dump" her. That's just one girl's opinion! Good luck :)
