Question

What happens during the fall in September?

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

Answer 1

Only statement 4 is correct.

- 1 is false — the Sun is highest in the sky at the summer solstice, not in September.
- 2 is false — at the September equinox the northern axis is neither tilted toward nor away from the Sun.
- 3 is false — daylight and night are about equal at the equinox, so the Northern Hemisphere does not have minimal daylight then.
- 4 is true — after summer the Sun’s rays strike the Northern Hemisphere less directly (less concentrated) than in summer, producing cooler conditions.
