Show the answer
Correct answer: c) It can never be negative.
Why it is correct
Altitude is measured from 0° to +90° above the horizon toward the zenith (in the visible hemisphere) and from 0° to −90° below the horizon toward the nadir (in the invisible hemisphere, e.g. the Sun during twilight). Saying it can never be negative is therefore incorrect.
Why the others are not
- a) Correct: it is measured from the true horizon to the body along its vertical circle.
- b) Correct: it is positive above the horizon and negative below it.
- d) Correct: its maximum absolute value is 90° (at the zenith or nadir).
How to work it out in the exam
- Altitude of a body: ranges from +90° (zenith) to −90° (nadir); it is negative below the horizon.
