North America is orange, South America is pink, Asia is yellow, Africa is green, Europe is red, Australia is brown and Antarctica is white.

Countries in both hemispheres Denmark (due to Greenland and the Faroe Islands; mainland Denmark lies entirely in the Eastern Hemisphere).

Any circle drawn around the Earth divides it into two equal halves called hemispheres. There are generally considered to be four hemispheres: Northern, Southern, Eastern, and Western….Vocabulary.

Those countries that are located entirely in the Western Hemisphere are: Iceland. Ireland. North Ireland.

Northern

The primary unit in which longitude and latitude are given is degrees (°). There are 360° of longitude (180° E ↔ 180° W) and 180° of latitude (90° N ↔ 90° S).

Important lines of latitude:

• the equator (0°)
• the Tropic of Cancer (23.5° north)
• the Tropic of Capricorn (23.5° south)
• the Arctic circle (66.5° north)
• the Antarctic circle (66.5° south)
• the North Pole (90° north)
• the South Pole (90° south)

The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

Latitude lines are comprehensive circles, with the middle at 0° and the pole at 90°. The South Pole and the North Pole have separated by 180° apart, The longitude lines cross from the North Pole to the South Pole. This is why it begins at zero and finishes at 360 longitudes.

The 180th meridian or antimeridian is the meridian 180° both east and west of the Prime Meridian, with which it forms a great circle dividing the earth into the Western and Eastern Hemispheres. It is common to both east longitude and west longitude.

“Longitude” goes 360 degrees, 180 East to 180 West, to cover the entire 360 degrees around the equator. But if latitude did the same thing, every point on the earth would be covered twice! So latitude only has to cover 180 degrees, from the north pole to the south pole.

parallels

Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels. A circle of latitude is an imaginary ring linking all points sharing a parallel.

Equator

Technically 90°N and 90°S are the shortest longitude on the Earth. Geographically, the 90°N is located in the middle of Arctic Ocean, while the South Pole 90°S is located in the middle of the continent Arctica. The 0° line (see the picture above), in fact, is the equator.

Prime Meridian

You can see the Meridian Line through the fence without paying the fee. Obviously, you can’t stand on it without paying to go in. You can get a discounted ticket for the Observatory plus the Cutty Sark for 18.50 pounds.

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.

The prime meridian divides Earth into the Eastern Hemisphere and the Western Hemisphere. The prime meridian is at 0° (0 degrees) longitude.

True Meridian. The true meridian passing through a station on surface of the earth is the (imaginary) line of intersection of a (imaginary) plane passing through the geographical North and South poles of the earth with its actual surface.

A (geographic) meridian (or line of longitude) is the half of an imaginary great circle on the Earth’s surface, a coordinate line terminated by the North Pole and the South Pole, connecting points of equal longitude, as measured in angular degrees east or west of the Prime Meridian.

There are several types of meridians: Astronomical or True, Magnetic, Grid, and Assumed. A plane passing through a point on the surface of the earth and containing the earth’s axis of rotation defines the astronomical or true meridian at that point.
