HEY FRNDThe 180th degree meridian is also called the anti meridian. It is used to define the International Date Line. Because the Earth is spherical, traveling 180 degrees in either direction from the prime meridian will lead to 180 degrees longitude or the opposite meridian.HOPE IT HELPS YOU

The 180° meridian is called the International Date Line. HAVE A VERY NICE DAYPLEASE FOLLOW ME

Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude. The distance around the Earth measures 360 degrees.The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees. It is the basis for the International Date Line.Half of the world, the Eastern Hemisphere, is measured in degrees east of the prime meridian. The other half, the Western Hemisphere, in degrees west of the prime meridian.Degrees of longitude are divided into 60 minutes. Each minute of longitude can be further divided into 60 seconds. For example, the longitude of Paris, France, is 2° 29' E (2 degrees, 29 minutes east). The longitude for Brasilia, Brazil, is 47° 55' W (47 degrees, 55 minutes west).A degree of longitude is about 111 kilometers (69 miles) at its widest. The widest areas of longitude are near the Equator, where the Earth bulges out. Because of the Earth's curvature, the actual distance of a degrees, minutes, and seconds of longitude depends on its distance from the Equator. The greater the distance, the shorter the length between meridians. All meridians meet at the North and South Poles.Longitude is related to latitude, the measurement of distance north or south of the Equator. Lines of latitude are called parallels. Maps are often marked with parallels and meridians, creating a grid. The point in the grid where parallels and meridians intersect is called a coordinate. Coordinates can be used to locate any point on Earth.Knowing the exact coordinates of a site (degrees, minutes, and seconds of longitude and latitude) is valuable for military, engineering, and rescue operations. Coordinates can give military leaders the location of weapons or enemy troops. Coordinates help engineers plan the best spot for a building, bridge, well, or other structure. Coordinates help airplane pilots land planes or drop aid packages in specific locations.WebsitesGeography for Kids: Latitude and Longitude Map Match GamePBS: Nova: Lost at Sea—The Search for LongitudeCredits User PermissionsRELATED RESOURCESConcept Of PlaceOne of the oldest tenants of geography is the concept of place. As a result, place has numerous definitions, from the simple “a space or location with meaning” to the more complex “an area having unique physical and human characteristics interconnected with other places.” There are three key components of place: location, locale, and a sense of place. Location is the position of a particular point on the surface of the Earth. Locale is the physical setting for relationships between people, such as the South of France or the Smoky Mountains. Finally, a sense of place is the emotions someone attaches to an area based on their experiences. Place can be applied at any scale and does not necessarily have to be fixed in either time or space. Additionally, due to globalization, place can change over time as its physical setting and cultures are influenced by new ideas or technologies.
