Consider the following statements about reading relief.
1. A V in the contours pointing uphill indicates a valley.
2. A saddle appears as an hourglass pattern of contours.
3. Closed contours always indicate a summit.

  • A.1 and 2 only
  • B.3 only
  • C.1 only
  • D.All of them

Answer: A

The first two are correct. The third ignores the hachured depression contour, which is also a closed loop but encloses ground falling inwards rather than rising. The inward ticks are the only thing that separates a crater from a hilltop on the sheet.
