Work on your own and answer these questions. 1. Name the line of longitude that the International Date Line is based on. 2. Why do countries adjust the International Date Line? 3. Explain why China should have five time zones. 4. If it is Wednesday in Fiii, what day is it in Hawaii? S. Explain why Fiii and Hawail have a different date.

1. The International Date Line is based on the 180° meridian. 2. Countries adjust the International Date Line to accommodate their geographical locations and time zones. The International Date Line is not a fixed line, but rather a line that passes through the middle of the Pacific Ocean, roughly following the 180° meridian. Countries that are located west of the International Date Line are considered to be one day ahead of countries that are located east of the line. This adjustment is necessary to ensure that each country has a consistent time zone and to avoid confusion when dealing with dates and times across different regions. 3. China should have five time zones because of its vast geographical size and the significant differences in time between the eastern and western parts of the country. China spans a large area, from the eastern coast to the western frontier, which results in a significant time difference between the two ends. Having five time zones would allow for more accurate and efficient timekeeping, especially in regions that are far apart. This would also facilitate communication and coordination between different parts of the country. 4. If it is Wednesday in Fiji, it would be Tuesday in Hawaii. 5. Fiji and Hawaii have a different date because they are located on opposite sides of the International Date Line. When it is Wednesday in Fiji, it is Tuesday in Hawaii, due to the one-day difference caused by crossing the International Date Line. This difference in date is a result of the International Date Line's purpose of separating two consecutive days.
