Topographic contour intervals

Answers and reasoning. Review before teaching.

  1. 1. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 400 m across 3 contour intervals uphill. What is the new elevation?

    430 m

    Elevation gain = 3 × 10 m = 30 m. New elevation = 400 m + 30 m = 430 m.

  2. 2. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 750 m across 2 contour intervals uphill. What is the new elevation?

    770 m

    Elevation gain = 2 × 10 m = 20 m. New elevation = 750 m + 20 m = 770 m.

  3. 3. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 100 m across 7 contour intervals uphill. What is the new elevation?

    450 m

    Elevation gain = 7 × 50 m = 350 m. New elevation = 100 m + 350 m = 450 m.

  4. 4. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 750 m across 7 contour intervals uphill. What is the new elevation?

    820 m

    Elevation gain = 7 × 10 m = 70 m. New elevation = 750 m + 70 m = 820 m.

  5. 5. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 700 m across 7 contour intervals uphill. What is the new elevation?

    1050 m

    Elevation gain = 7 × 50 m = 350 m. New elevation = 700 m + 350 m = 1050 m.

  6. 6. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 250 m across 5 contour intervals uphill. What is the new elevation?

    375 m

    Elevation gain = 5 × 25 m = 125 m. New elevation = 250 m + 125 m = 375 m.

  7. 7. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 450 m across 7 contour intervals uphill. What is the new elevation?

    520 m

    Elevation gain = 7 × 10 m = 70 m. New elevation = 450 m + 70 m = 520 m.

  8. 8. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 150 m across 4 contour intervals uphill. What is the new elevation?

    190 m

    Elevation gain = 4 × 10 m = 40 m. New elevation = 150 m + 40 m = 190 m.

  9. 9. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 400 m across 4 contour intervals uphill. What is the new elevation?

    480 m

    Elevation gain = 4 × 20 m = 80 m. New elevation = 400 m + 80 m = 480 m.

  10. 10. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 300 m across 2 contour intervals uphill. What is the new elevation?

    340 m

    Elevation gain = 2 × 20 m = 40 m. New elevation = 300 m + 40 m = 340 m.

  11. 11. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 50 m across 2 contour intervals uphill. What is the new elevation?

    70 m

    Elevation gain = 2 × 10 m = 20 m. New elevation = 50 m + 20 m = 70 m.

  12. 12. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 250 m across 7 contour intervals uphill. What is the new elevation?

    390 m

    Elevation gain = 7 × 20 m = 140 m. New elevation = 250 m + 140 m = 390 m.
