Time & Rhythms
References and resources are defined as sources of information that are found in such literary materials as books and periodicals and, in the modern world, are also available on the Internet. Time, which is one subject covered in reference materials, pertains to the measurable period during which an action, process or condition exists or continues. Similarly, rhythms refer to either movements that regularly occur over time or the natural flow of related elements. All over the world, there are several different time zones, which are longitudinal strips of the Earth extending from the north pole to the south pole that each have different times of day and night. This section features online resources on time and rhythms.
