Which of the following choices is located at 0 longitude? This question often arises when discussing the Prime Meridian, a crucial line of longitude that serves as a reference point for global positioning. In this article, we will explore the significance of the Prime Meridian and identify the correct choice among the options provided.
The Prime Meridian, also known as the Greenwich Meridian, runs through the Royal Observatory in Greenwich, London. It is the point where longitude is defined as 0 degrees. This line divides the Earth into the Eastern Hemisphere and the Western Hemisphere, with the International Date Line acting as a supplementary division that runs roughly 180 degrees away from the Prime Meridian.
Now, let’s examine the options to determine which one is located at 0 longitude:
1. The North Pole: The North Pole is not located at 0 longitude; it is situated at 90 degrees North latitude. Therefore, this option is incorrect.
2. The South Pole: Similarly, the South Pole is not located at 0 longitude; it is situated at 90 degrees South latitude. This option is also incorrect.
3. The Eiffel Tower: The Eiffel Tower is located in Paris, France, but it is not at 0 longitude. The longitude of the Eiffel Tower is approximately 2.3522 degrees East. Thus, this option is incorrect.
4. The Royal Observatory in Greenwich: This is the correct choice. The Royal Observatory in Greenwich, London, is located precisely at 0 degrees longitude. It was established in 1675 and has been the prime meridian since 1884. The Prime Meridian runs through the Royal Observatory, making it the point of reference for longitude measurements worldwide.
In conclusion, among the given choices, the Royal Observatory in Greenwich is the location that lies at 0 longitude. This point is of great importance in navigation, cartography, and global positioning systems, as it serves as a reference for determining the position of any place on Earth.
