Each of the 24 time zones consists of how many degrees?

Each of the 24 time zones is defined by a division of the Earth's circumference in degrees, with the Earth being roughly a sphere divided into 360 degrees. To determine the degree span of each time zone, you can divide the total degrees of the Earth by the number of time zones.

360 degrees divided by 24 time zones equals 15 degrees per time zone. This division allows for a uniform approach to time management across different regions of the globe, with each zone representing one hour of time change relative to Coordinated Universal Time (UTC).

Thus, the correct choice indicates that each time zone encompasses 15 degrees, which aligns with the standardized global timekeeping system used today.
