The Impact of Earth's Tilt on Daylight Hours
What is the relationship between the position of the sun in the sky and the amount of daylight hours?
A. The higher the sun in the sky, the longer the daylight hours.
B. The lower the sun in the sky, the longer the daylight hours.
C. The position of the sun does not affect daylight hours.
D. The position of the sun affects temperature, not daylight hours.
Answer:
The position of the sun in the sky does affect daylight hours. The higher the sun's position, the longer the daylight, while a lower position results in shorter daylight hours.
The correlation between the position of the sun in the sky and the amount of daylight hours is significant. The higher the sun in the sky, the longer the daylight hours. This phenomenon is due to Earth's 23.5º tilt of the axis of rotation.
On a solstice day when the Sun is highest in the sky, it can stay present for up to 15 hours in the Northern Hemisphere. In contrast, in winter when the Sun is low in the sky, we have less daylight. The Sun's rays come at a more horizontal angle during this time, resulting in less than 12 hours of daytime.
The position of the Sun changes slightly every day, moving eastwards relative to the stars. This apparent movement is a result of Earth's orbit around the sun rather than the Sun's orbit around the Earth.
Due to Earth's tilted axis, the orbit results in changes in the sun's position in our sky, leading to the variation in daylight hours that we experience throughout the year.
