The Equator line is an imaginary line responsible for dividing the globe into two hemispheres:
Southern Hemisphere, also called southern or southern.
Northern Hemisphere, also known as Northern or Boreal.
The distance of any point on the earth's surface in relation to the equator is called latitude, and is given in degrees. Therefore, it is defined as 0° the latitude of the equator. The northern and southern hemispheres have, respectively, north latitude (N) and south latitude (S), which measure up to 90°.
There are four other important parallels: the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere, and the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere.
The Equator line has a length of 40,000 kilometers, present in the entire circumference of the Earth, passes through the central-southern stretch of America, through the central portion of Africa and through the extreme south of the Asia.
The countries where the equator line is present are:
• Saint Thomas
• Gabon
• Democratic Republic of Congo
• Uganda
• Kenya
• Somalia
• Maldives
• Indonesia
• Kiribati
• Ecuador
• Colombia
• Brazil.
In Brazilian territory there is only one capital that is cut by the parallel of Ecuador, that is Macapá, located in the State of Amapá.
