Topographic contour intervals

Answers and reasoning. Review before teaching.

1. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 250 m across 8 contour intervals uphill. What is the new elevation?
410 m
Elevation gain = 8 × 20 m = 160 m. New elevation = 250 m + 160 m = 410 m.
2. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 450 m across 7 contour intervals uphill. What is the new elevation?
625 m
Elevation gain = 7 × 25 m = 175 m. New elevation = 450 m + 175 m = 625 m.
3. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 250 m across 6 contour intervals uphill. What is the new elevation?
550 m
Elevation gain = 6 × 50 m = 300 m. New elevation = 250 m + 300 m = 550 m.
4. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 500 m across 3 contour intervals uphill. What is the new elevation?
650 m
Elevation gain = 3 × 50 m = 150 m. New elevation = 500 m + 150 m = 650 m.
5. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 350 m across 7 contour intervals uphill. What is the new elevation?
420 m
Elevation gain = 7 × 10 m = 70 m. New elevation = 350 m + 70 m = 420 m.
6. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 450 m across 4 contour intervals uphill. What is the new elevation?
650 m
Elevation gain = 4 × 50 m = 200 m. New elevation = 450 m + 200 m = 650 m.
7. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 450 m across 8 contour intervals uphill. What is the new elevation?
650 m
Elevation gain = 8 × 25 m = 200 m. New elevation = 450 m + 200 m = 650 m.
8. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 50 m across 5 contour intervals uphill. What is the new elevation?
100 m
Elevation gain = 5 × 10 m = 50 m. New elevation = 50 m + 50 m = 100 m.
9. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 500 m across 2 contour intervals uphill. What is the new elevation?
600 m
Elevation gain = 2 × 50 m = 100 m. New elevation = 500 m + 100 m = 600 m.
10. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 200 m across 4 contour intervals uphill. What is the new elevation?
300 m
Elevation gain = 4 × 25 m = 100 m. New elevation = 200 m + 100 m = 300 m.
11. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 650 m across 6 contour intervals uphill. What is the new elevation?
710 m
Elevation gain = 6 × 10 m = 60 m. New elevation = 650 m + 60 m = 710 m.
12. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 500 m across 5 contour intervals uphill. What is the new elevation?
550 m
Elevation gain = 5 × 10 m = 50 m. New elevation = 500 m + 50 m = 550 m.
