Explanation / Answer

Q) How does the changing position of the Sun on the ecliptic affect our view of the Sun in our local sky at different locations on Earth?

Ans. A. In the Northern Hemisphere, the length of the day is shorter in December than it is in June.

B. At latitudes closer to the poles, the difference in the Sun’s illumination throughout the year is more extreme.

C. In the Northern Hemisphere, the Sun is lower in the sky in December than it is in June.

At June 21 (Summer solstice) the length of the day in the Northern Hemisphere is maximum. At September 22-23 (Autumnal equinox) the length of the day and night all over the Earth is same. At December 21 (Winter solstice) the lenghth of day in the Southern Hemisphere is maximum. At March 21-22 (Vernal equinox) the length of the day and night all over the Earth is same.

So,  In the Northern Hemisphere, the length of the day is shorter in December than it is in June is correct.

Latitude closer to the poles get sun light only for six months and other six months those locations are not illuminated. So, at latitudes closer to the poles, the difference in the Sun’s illumination throughout the year is more extreme is correct. And at latitudes near the equator, the difference in the Sun’s illumination throughout the year is more extreme is not correct.

The length of day in the Northern Hemisphere is greater In June than December. And in the Southern Hemisphere the length of day is greater in December than in June. So, In the Northern Hemisphere, the Sun is lower in the sky in December than it is in June is correct. And in the Southern Hemisphere, the Sun is lower in the sky in December than it is in June is not correct.

The Sun always rises directly east and sets directly west is not correct. There is only two days September 22-23 and March 21-22 when Sun rises directly east and sets directly west.

Thats all

Thank you.
