A gradient of 037 implies that
O the slope is steeper than another location with a gradient of 040.
O neither a topographic nor a shaded-relief map can be constructed for the area because the gradient is too small.
O there are .037 times as many Index contours as there are other contours on the map.
O the slope will drop by 37 meters (or feet or Inches) for every 1.000 meters (or feet or Inches) of horizontal distance.
