Question

part (b) which of the following statements accurately describes how a star’s azimuth and altitude change in your view looking toward the eastern horizon? altitude increases, azimuth increases; altitude decreases, azimuth increases; altitude decreases, azimuth decreases; it is impossible to tell from this view; altitude increases, azimuth decreases

Explanation:

To solve this, we recall the concepts of azimuth (horizontal direction, measured from north, eastward is positive) and altitude (angle above the horizon) for a star rising in the east. As a star rises from the eastern horizon, it moves upward (so altitude increases) and as it moves across the sky towards the south - east to south - west path (but initially, when looking east, as it rises, its azimuth (since we measure azimuth from north, moving east - to - south - east, the azimuth angle from north increases) also increases. So the correct statement is "Altitude increases, azimuth increases".

Answer:

A. Altitude increases, azimuth increases
