With an aid of diagrams describe azimuthal and conical map projections, giving advantages and disadvantages of using them

Which of the following is false about the characteristics of contour lines? Select the correct response: Contours are perpendicular to the direction of maximum slope. The direction of rainfall run-off in a map area can be determined from this characteristic. Contour lines are irregularly spaced on uniformly sloping ground. Contour lines tend to parallel streams. Rivers usually have a flatter gradient than do intermittent streams. Each contour line must close upon itself either within or outside the borders of the map. A series of closed contour lines represents either a hill or depression. The elevations of the index contour lines will indicate which series represents a hill and which represents a depression.
