class 6 Social Science Textbook Chapter 1 question answer
Local time is closely related to longitude due to the Earth’s rotation, which causes different areas to experience daylight and darkness at different times. The Earth rotates 360 degrees in approximately 24 hours, so each time zone covers about 15 degrees of longitude, corresponding to one hour’s difference in time. Standard time is often based on the mean solar time at a specific meridian, with Coordinated Universal Time (UTC) serving as a reference point for establishing time zones across the globe.
