70% to passWhen taking an amplitude, the Sun's center should be observed on the visible horizon when _______________.
A
in high latitudes
B
the Sun's declination is at or near 0°
C
the Sun is near or at a solstice
D
the declination is of a different name from the latitude
AI Explanation
The correct answer is A) in high latitudes. When taking an amplitude measurement using the Sun, the Sun's center should be observed on the visible horizon when in high latitudes. This is because in high latitudes, the Sun's altitude is low, allowing its center to be observed on the visible horizon more easily. The other answer choices are incorrect because they do not specifically address the need for high latitudes to properly observe the Sun's center on the horizon when taking an amplitude measurement.
