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 66° N (using 90° − latitude)?

    24°

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

  2. 2. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 68° N (using 90° − latitude)?

    22°

    At the equinox, noon solar elevation = 90° − 68° = 22°.

  3. 3. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 42° N (using 90° − latitude)?

    48°

    At the equinox, noon solar elevation = 90° − 42° = 48°.

  4. 4. 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°.

  5. 5. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 22° N (using 90° − latitude)?

    68°

    At the equinox, noon solar elevation = 90° − 22° = 68°.

  6. 6. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 37° N (using 90° − latitude)?

    53°

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

  7. 7. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 64° N (using 90° − latitude)?

    26°

    At the equinox, noon solar elevation = 90° − 64° = 26°.

  8. 8. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 33° N (using 90° − latitude)?

    57°

    At the equinox, noon solar elevation = 90° − 33° = 57°.

  9. 9. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 24° N (using 90° − latitude)?

    66°

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

  10. 10. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 48° N (using 90° − latitude)?

    42°

    At the equinox, noon solar elevation = 90° − 48° = 42°.

  11. 11. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 38° N (using 90° − latitude)?

    52°

    At the equinox, noon solar elevation = 90° − 38° = 52°.

  12. 12. At the equinox, the sun is directly overhead at the Equator (0°). What is the noon solar elevation angle at latitude 67° N (using 90° − latitude)?

    23°

    At the equinox, noon solar elevation = 90° − 67° = 23°.
