1.If the inclination angle is zero, how does the path of the Sun in the sky change as the planet moves from the right side of its orbit to the left? What is the longest duration (in hours) of sunlit time during the year? What is the shortest duration of sunlit time? How does the angle of sunlight striking the ground change? What is the change in average temperature?
The path of the Sun in the sky doesn’t change as the planet moves from the right side of its orbit to the left. The longest and shortest duration of sunlit time is 12 hours. The angle of the sunlight doesn’t change on the ground. The average temperature stays the same with warm climate throughout the year.
2.Modify the inclination angle to 23 degrees and watch for a complete revolution. What is the length of the longest and shortest duration of sunlit times now? How does the angle of sunlight striking the ground change? What is the change in average temperature now?
The length of the longest sunlit time is approx. 15 hours and the shortest is approx. 9 hours. The angle of sunlight changes during the winter and summer months.
3.Modify the inclination angle to 60 degrees. Watch the position of the Sun and the brightness of the sky over the landscape carefully. What are the longest and shortest duration of sunlit time now? What is the change in average temperature over the course of a year?
The longest period of sunlight that lasts for more than 24hrs is when the inclination angle is about 60 degrees with the shortest time of sunlight being zero hours. The average change of temperature from winter to summer is greater than that of a 23 degree tilt.
4. What is the smallest inclination angle which leads to a 24-hour period without sunlight?
At 45 degrees, this is the smallest inclination angle that leads to 24hrs of night.
5. The planet Uranus is tilted nearly on its side, so that its axis of rotation is only 8 degrees away from its orbital plane. If you lived at...
