True

Important facts on Parallels and Meridians:

Parallels of Latitude: The parallels of latitude are the boundary lines of imaginary circles drawn around the earth. They run in the east-west direction and are parallel to each other. Parallels are of different length. Equator is the longest parallel and it divides the earth into the Northern Hemisphere and Southern Hemisphere.The parallels are numbered. The equator is marked zero degree. The North Pole and the South Pole is marked 90 degree North and 90 degree South respectively.Arctic Circle and Tropic of Cancer parallel lie between North Pole and the equator.Antarctic Circle and Tropic of Capricorn parallel lie between South Pole and the equator.

Meridians of Longitude: Meridian is an imaginary semicircle that runs in the north-south direction and joins the two poles. All meridians are of the same length and meet at the poles.Prime Meridian is an imaginary line which divides the earth into eastern and western hemispheres. It is sometimes referred to as the Greenwich Meridian. The Prime Meridian which passes through Greenwich, England, is considered 0 degrees longitude.Places on different meridians have a time difference because they have sunrise and sunset at different times.

International Date Line: The longitude at 180 degrees from the Greenwich Time Line is known as International Date Line. It was designated in 1884. If you travel west from the International Date Line, you add a day, and if you travel east from the International Date Line, you subtract a day.
