उत्तर
| Sr. No. | Basis | Vertical Interval (V.I.) | Horizontal Equivalent (H.E.) |
| 1. | Meaning | The vertical height between two contour lines. | The horizontal distance between two contour lines. |
| 2. | Measurement | Measured in metres or feet (elevation difference). | Measured in metres or cm on map (ground distance). |
| 3. | Indicates | Change in height. | Slope steepness (steeper = shorter H.E.). |
| 4. | Remains | Always constant on a given map. | Varies based on land slope. |
| 5. | Example | If V.I. = 20 m, each contour is 20 m higher or lower. | If contours are close together, H.E. is small = steep slope. |
