Question

Distinguish between vertical interval and horizontal equivalent​ (3 points)

Answer 1

vertical interval

1)It is based on vertical levels

2)No measurement or scaling is required since the contour levels are indicated on the contour lines

3)in a given map the contour interval is a constant

horizontal interval

1)Represents horizontal distance

2)The distance must be measured on the map and converted to actual distance by multiplying with the scale of the map

3)The horizontal equivalent varies with slope. Closer distance indicates steep slope and wider distance gentle slope
