Lines of longitude are imaginary lines which run in a north-south direction from the North Pole to the South Pole. The lines are called meridians of longitude and they are also measured in degrees (°) and minutes (‘). The most important line of longitude is the Greenwich or Prime Meridian (0°) .
What is the important line of longitude?
All three lines of latitude are significant in their relationship between Earth and the sun. Running in the opposite direction, north-south, the prime meridian is one of the most important lines of longitude on Earth.
What are the 2 main lines of longitude?
1. Prime Meridian = Longitude 0 o (Greenwich Meridian). 2. International Date Line (Longitude 180 o ) .
What are the two 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)
How many important lines are there in longitude?
There are 360 meridians – 180 to the east and 180 to the west of the Prime Meridian. The meridians in the Eastern Hemisphere are marked as ‘E' and meridians in the Western Hemisphere are marked as ‘W'. The meridian of 180 ̊ E and meridian of 180 ̊ W are in the same line.
What are the 7 major lines of longitude?
- North Pole.
- Arctic Circle.
- Tropic of Cancer.
- Equator.
- Tropic of Capricorn.
- Antarctic circle.
- South Pole.
What is the Globe Class 6?
A globe is a spherical figure which is a miniature form of earth . It gives us a three-dimensional view of the whole Earth by showing distances, directions, areas, etc. ... The globe provides 3-D (three-dimensional view) of the entire Earth. The latitudes and longitudes are shown on the globe as circles or semi-circles.
What is the 0 line of longitude?
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. It is the basis for the International Date Line.
What are the 5 major lines of longitude?
The five major parallels of latitudes from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle . Five major parallels of latitudes. Image: NASA, public domain.
Which two lines of longitude is Jamaica nearest to?
The geographical alignment of Jamaica includes latitude of 18° 15′ N and longitude of 77° 30′ W . The particular latitude of Jamaica shows its position in Northern Hemisphere and its moderate proximity to the equator.
How many longitudes are there in total?
To measure longitude east or west of the Prime Meridian, there are 180 vertical longitude lines east of the Prime Meridian and 180 vertical longitude lines west of the Prime Meridian, so longitude locations are given as __ degrees east or __ degrees west.
Why there are 180 latitudes and 360 longitudes?
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.
What is difference between longitude and latitude?
| Latitude Longitude | It is known as parallels It is known as meridians | The length of the lines are different The length of the lines are the same |
|---|
Which is the longest parallel?
The Equator is the longest parallel. It divides the Earth into two equal halves. Lines of longitude are also called meridians.
What distance is 1 degree of longitude?
One-degree of longitude equals 288,200 feet (54.6 miles) , one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet.
How do you calculate longitude?
The Earth rotates one full turn (360o of longitude) in one day. It therefore turns one degree of longitude in 1/360th of a day, or every four minutes. To calculate your longitude, you therefore simply need to work out the time difference between noon at your location and noon at the Prime Meridian .
