Longitudes are angular distances east or west of the prime meridian. Longitudes are also called Meridians. The Prime Meridian passes through Greenwich, in England.

Some Important Longitudes include:

1. Prime Meridian = Longitude 0o (Greenwich Meridian).

2. International Date Line (Longitude 180o).

Characteristics of Longitudes

1. Each meridian is half of a great circle.

2. They run in a true north-south direction from

connecting the North and South Poles.

3. They are spaced farthest apart at the equator but

converges at the poles.

4. Meridians help us to determine standard time.

LATITUDES angular distances East or West of the Equator. Latitudes are also called Parallels.

Longitudes and Latitudes are expressed in degrees, minutes and seconds.

Some Important Latitudes:

1. Equator (Latitude 0o)

2. Tropic of Cancer (Latitude 23.5oN)

3. Tropic of Capricorn (Latitude 23.5oS)

4. Arctic Circle (Latitude 66.5oN).

5. Antarctic Circle (Latitude 66.5oS).
