Altitude & temperature lapse rate

Answers and reasoning. Review before teaching.

  1. 1. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 15° N (using 90° − latitude)?

    75°

    At the equinox, noon solar elevation = 90° − 15° = 75°.

  2. 2. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 19° N (using 90° − latitude)?

    71°

    At the equinox, noon solar elevation = 90° − 19° = 71°.

  3. 3. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 35° N (using 90° − latitude)?

    55°

    At the equinox, noon solar elevation = 90° − 35° = 55°.

  4. 4. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 56° N (using 90° − latitude)?

    34°

    At the equinox, noon solar elevation = 90° − 56° = 34°.

  5. 5. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 61° N (using 90° − latitude)?

    29°

    At the equinox, noon solar elevation = 90° − 61° = 29°.

  6. 6. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 53° N (using 90° − latitude)?

    37°

    At the equinox, noon solar elevation = 90° − 53° = 37°.

  7. 7. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 9° N (using 90° − latitude)?

    81°

    At the equinox, noon solar elevation = 90° − 9° = 81°.

  8. 8. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 75° N (using 90° − latitude)?

    15°

    At the equinox, noon solar elevation = 90° − 75° = 15°.

  9. 9. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 8° N (using 90° − latitude)?

    82°

    At the equinox, noon solar elevation = 90° − 8° = 82°.

  10. 10. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 66° N (using 90° − latitude)?

    24°

    At the equinox, noon solar elevation = 90° − 66° = 24°.

  11. 11. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 51° N (using 90° − latitude)?

    39°

    At the equinox, noon solar elevation = 90° − 51° = 39°.

  12. 12. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 18° N (using 90° − latitude)?

    72°

    At the equinox, noon solar elevation = 90° − 18° = 72°.
