How are time zones determined?

By geographical features.
By longitudinal lines.
By the seasons of the year.
By latitudinal measurements.

The correct answer is: By longitudinal lines.

Time zones are primarily determined by longitudinal lines. The Earth is divided into 360 degrees of longitude, and as the Earth rotates on its axis, different regions experience daylight and darkness at different times. To standardize timekeeping across various locations, the world is divided into time zones that generally follow lines of longitude, with each time zone typically representing one hour of time difference based on the Earth's rotation. While geographical features can influence the exact boundaries of time zones, the foundational concept relies on longitudinal measurements that dictate how far east or west a location is from the Prime Meridian (0 degrees longitude). This reflects the natural way day and night cycle due to the Earth's rotation. The seasons and latitudinal measurements have their own significance in geography and climate but do not directly establish time zones.
