3 lengte en breetelyne
The document provides information about longitude and latitude lines and how they divide the Earth. It discusses the following key points: - Longitude and latitude lines divide the Earth into four hemispheres. The equator (0° latitude) divides the north and south hemispheres, and the Greenwich meridian and 180° longitude line divide the east and west hemispheres. - Longitude lines run north-south and are measured in degrees and minutes from 0° at the Greenwich meridian. They indicate locations east or west. Latitude lines run east-west parallel to the equator and indicate locations north and south. - Coordinates using degrees of longitude and latitude are used to indicate precise locations on Earth. The intersection of the

- 19. There are25 integer World Time Zones from -12 through 0 (GMT) to +12. Each one is 15° of Longitude as measured East and West from the Prime Meridian of the World at Greenwich, England. Some countries have adopted non-standard time zones, usually 30 minutes offset which have a * designation.
- 20. GMT isan absolute time reference and does not change with the seasons. London time is the same as Greenwich Mean Time less than half of the year. GMT was established in 1884 at the International Meridian Conference, when it was decided to the place the Prime Meridian at Greenwich, England.

- 22. •Over the years,the position of the International Date Line has changed several times. Until 1845, the Philippines were on the eastern side of it. When the United States bought Alaska in 1867 the line was moved to the west of it. •The most recent change in the line was in 1995 when Kiribati moved a large segment of it to the east, so that the entire nation would be on the same side of the International Date Line.
- 23. Let's sayyou fly from the United States to Japan. Let's suppose you leave the United States on Tuesday morning. Since you're traveling west the time advances slowly thanks to time zones and the speed at which your airplane flies, but once you cross the International Date Line, it's suddenly Wednesday. On the reverse trip home you fly from Japan to the United States. You leave Japan on Monday morning but as you cross the Pacific Ocean, the day gets later quickly as you cross time zones moving eastward in an airplace. However, once you cross the International Date Line, the day changes to Sunday.
