What is the International Date Line? Describe its importance.
The International Date Line is an imaginary line on the Earth’s surface that roughly follows the 180th meridian and marks the place where the date changes by one day when crossing from east to west or vice versa.
Its importance is as follows:
- It marks the place where the date changes by one day when crossing from east to west or vice versa.
- It serves as the reference line for calculating time differences between different parts of the world.
- It is important for navigation and communication, as it helps to synchronize time across different time zones and prevent confusion.
- The location of the International Date Line can cause some areas to be a day ahead or behind, depending on which side of the line they are on.
