Describe how the amount of daylight hours change throughout the year.
Winter has the shortest day of the year. Daylight then increases through spring until we have the longest day of the year in summer. From there, it slowly decreases through fall until we get to the shortest day of the year again in winter.
Why is there a difference in the length of daylight throughout the year?
Our tilted axis
