Q1:

The direction of steepest slope on a contour, is

A along the contour

B at an angle of 45° to the contour

C at right angles to the contour

D none of these.

ANS:C - at right angles to the contour


Just consider one point on one contour line and 2, 3 points on the consecutive contour line. The perpendicular line will be the steepest. Work pot and check on paper. Contour lines are horizontal. Slope angle I think >0 to 90 degree.
So steepest slope should be 90°. So, the right angles to contour.
