Topographic contour intervals

Answers and reasoning. Review before teaching.

  1. 1. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 550 m across 5 contour intervals uphill. What is the new elevation?

    675 m

    Elevation gain = 5 × 25 m = 125 m. New elevation = 550 m + 125 m = 675 m.

  2. 2. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 200 m across 7 contour intervals uphill. What is the new elevation?

    550 m

    Elevation gain = 7 × 50 m = 350 m. New elevation = 200 m + 350 m = 550 m.

  3. 3. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 400 m across 4 contour intervals uphill. What is the new elevation?

    440 m

    Elevation gain = 4 × 10 m = 40 m. New elevation = 400 m + 40 m = 440 m.

  4. 4. 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.

  5. 5. 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.

  6. 6. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 550 m across 2 contour intervals uphill. What is the new elevation?

    650 m

    Elevation gain = 2 × 50 m = 100 m. New elevation = 550 m + 100 m = 650 m.

  7. 7. On a topographic map, the contour interval is 20 m. A hiker climbs from contour line 350 m across 4 contour intervals uphill. What is the new elevation?

    430 m

    Elevation gain = 4 × 20 m = 80 m. New elevation = 350 m + 80 m = 430 m.

  8. 8. On a topographic map, the contour interval is 50 m. A hiker climbs from contour line 100 m across 8 contour intervals uphill. What is the new elevation?

    500 m

    Elevation gain = 8 × 50 m = 400 m. New elevation = 100 m + 400 m = 500 m.

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

    300 m

    Elevation gain = 5 × 50 m = 250 m. New elevation = 50 m + 250 m = 300 m.

  10. 10. On a topographic map, the contour interval is 10 m. A hiker climbs from contour line 400 m across 2 contour intervals uphill. What is the new elevation?

    420 m

    Elevation gain = 2 × 10 m = 20 m. New elevation = 400 m + 20 m = 420 m.

  11. 11. On a topographic map, the contour interval is 25 m. A hiker climbs from contour line 450 m across 3 contour intervals uphill. What is the new elevation?

    525 m

    Elevation gain = 3 × 25 m = 75 m. New elevation = 450 m + 75 m = 525 m.

  12. 12. 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.
