Globe Latitudes and Longitudes: Latitudes and longitudes help create a grid system that enables us to identify any point on Earth’s surface with precision. They are fundamental to cartography, navigation, and geographic information systems.
Globe Latitudes and Longitudes
Latitudes and longitudes are geographical coordinates used to specify locations on the Earth’s surface. They are essential for navigation, mapping, and accurately pinpointing places on the globe. Here’s a brief explanation of latitudes and longitudes:
- Latitudes are horizontal lines that run east-west and are also known as parallels.
- They measure the distance north or south of the Equator, which is designated as 0 degrees latitude.
- Latitudes north of the Equator are designated with the letter “N” (for North), while those south of the Equator are designated with the letter “S” (for South).
- The maximum latitude is 90 degrees, which is the North Pole (90 degrees N) or the South Pole (90 degrees S).
- Latitudes are further divided into minutes and seconds (1 degree = 60 minutes, 1 minute = 60 seconds).
Important Parallels of Latitudes
- Tropic of Cancer (23½° N) in the Northern Hemisphere
- Tropic of Capricorn (23½° S) in the Southern Hemisphere
- Arctic Circle at 66½° north of the equator
- Antarctic Circle at 66½° south of the equator
- Longitudes are vertical lines that run north-south and are also known as meridians.
- They measure the distance east or west of the Prime Meridian, which is designated as 0 degrees longitude. The Prime Meridian passes through the Royal Observatory in Greenwich, London, and is also known as the Greenwich Meridian.
- Longitudes to the east of the Prime Meridian are designated with the letter “E” (for East), while those to the west are designated with the letter “W” (for West).
- The maximum longitude is 180 degrees (180 degrees E or 180 degrees W), which corresponds to the International Date Line.
- Longitudes are also divided into minutes and seconds.
- To specify a location, you use both latitude and longitude coordinates. For example, New York City is approximately located at 40.7128 degrees N (latitude) and 74.0060 degrees W (longitude).
- Coordinates are typically written in the format “latitude, longitude.” For example, the coordinates for the Great Pyramid of Giza are approximately 29.9792 degrees N, 31.1342 degrees E.
