天文學問題 (請解答之餘附上解釋)

1. It actually depends on the time (season) of the year. Since HK is of latitutde 22.5 deg north, most of the time the sun is located to the south of HK. Hence, I would select line B.

Likewise, line S is the best option.

2. (a) If the earth did not spin, "one day" would becomes 2 months (1 calendar year) long.

In that case, the sun appeared to rise from the west and to set on the east.

(b)(i) The daily motion of the sun is due to earth rotation. Hence, both the sun and the Ecliptic will shift a bit downward on the window view.

(ii) After one day, the sun moves along the Ecliptic because of the revolution of the earth. Thus, the window view shows that the sun goes up a bit along the Ecliptic.

我不明白Bi esliptic 的位置??
可以劃給我???
