Topographic contour intervals

Answers and reasoning. Review before teaching.

1. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 400 m across 3 contour intervals uphill. What is the new elevation?
475 m
Elevation gain = 3 × 25 m = 75 m. New elevation = 400 m + 75 m = 475 m.
2. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 150 m across 2 contour intervals uphill. What is the new elevation?
170 m
Elevation gain = 2 × 10 m = 20 m. New elevation = 150 m + 20 m = 170 m.
3. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 450 m across 6 contour intervals uphill. What is the new elevation?
600 m
Elevation gain = 6 × 25 m = 150 m. New elevation = 450 m + 150 m = 600 m.
4. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 750 m across 7 contour intervals uphill. What is the new elevation?
890 m
Elevation gain = 7 × 20 m = 140 m. New elevation = 750 m + 140 m = 890 m.
5. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 500 m across 8 contour intervals uphill. What is the new elevation?
660 m
Elevation gain = 8 × 20 m = 160 m. New elevation = 500 m + 160 m = 660 m.
6. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 300 m across 4 contour intervals uphill. What is the new elevation?
400 m
Elevation gain = 4 × 25 m = 100 m. New elevation = 300 m + 100 m = 400 m.
7. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 150 m across 5 contour intervals uphill. What is the new elevation?
400 m
Elevation gain = 5 × 50 m = 250 m. New elevation = 150 m + 250 m = 400 m.
8. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 100 m across 8 contour intervals uphill. What is the new elevation?
260 m
Elevation gain = 8 × 20 m = 160 m. New elevation = 100 m + 160 m = 260 m.
9. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 750 m across 7 contour intervals uphill. What is the new elevation?
1100 m
Elevation gain = 7 × 50 m = 350 m. New elevation = 750 m + 350 m = 1100 m.
10. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 700 m across 3 contour intervals uphill. What is the new elevation?
775 m
Elevation gain = 3 × 25 m = 75 m. New elevation = 700 m + 75 m = 775 m.
11. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 200 m across 7 contour intervals uphill. What is the new elevation?
270 m
Elevation gain = 7 × 10 m = 70 m. New elevation = 200 m + 70 m = 270 m.
12. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 750 m across 4 contour intervals uphill. What is the new elevation?
830 m
Elevation gain = 4 × 20 m = 80 m. New elevation = 750 m + 80 m = 830 m.
