Question

For an observer at a northern latitude, when the North Pole is tilted towards the Sun, the day lasts:

• A. longer and the Sun appears lower in the sky
• B. shorter and the Sun appears higher in the sky
• C. longer and the Sun appears higher in the sky
• D. shorter and the Sun appears lower in the sky

Hint:

During summer in the Northern Hemisphere, days are longer and the Sun appears higher due to Earth's axial tilt.

Answer 1

The Correct Option is C

To determine how the day length and Sun's position change for an observer at a northern latitude when the North Pole is tilted towards the Sun, we analyze the Earth's axial tilt and its effects.

1. Understanding Earth's Tilt and Seasons:
When the North Pole is tilted towards the Sun, it is summer in the Northern Hemisphere. This occurs around the June solstice.

2. Effect on Day Length:
- The tilt causes the Northern Hemisphere to receive more direct sunlight, leading to longer daylight hours.
- The farther north the observer is, the longer the day lasts (e.g., the Arctic Circle experiences 24 hours of daylight).

3. Effect on Sun's Apparent Height:
- The Sun appears higher in the sky because the Northern Hemisphere is angled towards it.
- The solar altitude at noon is higher compared to other times of the year.

Conclusion:
For an observer in the Northern Hemisphere during this time, the days are longer, and the Sun appears higher in the sky.

Final Answer:
The correct option is: longer and the Sun appears higher in the sky.
