Question

What happens during the fall in September?

AThe Sun is at its highest point in the sky.
BThe northern end of Earth’s axis is tilted toward the Sun.
CThe Northern Hemisphere receives minimal daylight hours.
DThe Sun’s rays are not as concentrated as in summer.

Answer 1

Answer:

The Sun’s rays are not as concentrated as in summer.

Explanation:

During the fall in September, the Sun passes from northern hemisphere towards equator. Equinox occurs around September 22. On this day, Sunlight directly falls on the equator i.e. the sun crosses celestial equator. Day time is equal to night time in the two hemispheres.  

Thereafter, the daylight decreases in northern hemisphere and increases in southern hemisphere. This is because the sun rays are not concentrated as much as in Summers in Northern hemisphere. In summers, the Sun crosses the tropic of cancer on the day of solstice.

Answer 2

1. The Sun moves from the northern hemisphere to the equator in September.
2. The Autumn Equinox occurs around September 22nd.
3. On this day, sunlight falls directly on the equator, indicating that the sun has crossed the celestial equator. In both hemispheres, daytime equals nighttime.
4. Following that, daylight decreases in the northern hemisphere and increases in the southern hemisphere.
5. This is because the sun's rays are not as concentrated as they are in the Northern Hemisphere during the summer.

Hence, option D is correct.
