View solution

Q. To contour lines having the same elevations cannot unite and continue as one line.

View solution

Q. A single contour line can split into two in case of a change in elevations.

View solution

View solution

Q. Contour lines cross a watershed or ridge line at _____

View solution

Q. What is the shape of contour lines in case of a valley?

View solution

Q. What is the shape of contour lines in case of a watershed?

View solution

Q. The same contour appears on either sides of a ridge or valley, for the highest horizontal plane that interests the ridge must cut it on both sides.

View solution

Q. What is the process of spacing the contours proportional between the plotted ground points established by indirect methods?

View solution

Q. The methods of interpolation are based on the assumption that the slope of ground between the two points is uniform.
