Globe Latitudes and Longitudes Class 6 Notes Geography | DailyHomeStudy

Overview

Globes are of various sizes and types such as big ones, small pocket globes, and globe-like balloons. The globe is not fixed and can be rotated the same way as a topspin or a potter’s wheel is rotated. On the globe, countries, continents and oceans are shown in their correct size.

A needle is fixed through the globe in a tilted manner, which is called its axis. Two points on the globe through which the needle passes are two poles – North Pole and South Pole.

The globe can be moved around this needle from west to east just as the earth moves. But, there is a major difference. The real earth moves around its axis, which is an imaginary line. Another imaginary line running on the globe divides it into two equal parts. This line is known as the equator. The northern half of the earth is known as the Northern Hemisphere and the southern half is known as the Southern Hemisphere. They are both equal halves.

The equator is an imaginary circular line to locate places on the earth. All parallel circles from the equator up to the poles are called parallels of latitudes. Latitudes are measured in degrees.

The equator represents the zero degree latitude. Since the distance from the equator to either of the poles is one-fourth of a circle round the earth, it will measure ¼th of 360 degrees, i.e. 90°. Thus, 90 degrees north latitude marks the North Pole and 90 degrees south latitude marks the South Pole.

All parallels north of the equator are called ‘north latitudes.’ Similarly all parallels south of the equator are called ‘south latitudes.’ The value of each latitude is, indicated by the letter ‘N’ or ‘S’.

Important Parallels of Latitude

There are four important parallels of latitudes

  1. Tropic of Cancer (23½° N) in the Northern Hemisphere.
  2. Tropic of Capricorn (23½° S) in the Southern Hemisphere.
  3. Arctic Circle at 66½° north of the equator.
  4. Antarctic Circle at 66½° south of the equator.
