As you examine the diagram, keep in mind that Earth is always rotating, even though the diagrams do not show this rotation because they are not animated. Each of the following figures shows Earth with a different axis tilt. (Assume that Earth's rotation period is unchanged.) Each also shows a person located in Florida (not to scale). Rank the figures based on how much time the person spends in daylight during a 24-hour period, from most to least.
