What is the imaginary line called?
Imaginary lines, also called meridians, running vertically around the globe. Unlike latitude lines, longitude lines are not parallel. Meridians meet at the poles and are widest apart at the equator. Zero degrees longitude (0°) is called the prime meridian.
How many imaginary lines does longitude have?
180 imaginary lines It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels.
What are the 5 imaginary lines of latitude?
The five major latitude lines are the equator, the Tropics of Cancer and Capricorn, and the Arctic and Antarctic Circles.
What are the 3 imaginary lines on Earth?
The Equator, Tropics, and Prime Meridian All three lines of latitude are significant in their relationship between Earth and the sun.
What are longitude lines also called?
Lines of longitude, also called meridians, are imaginary lines that divide the Earth. They run north to south from pole to pole, but they measure the distance east or west. Longitude is measured in degrees, minutes, and seconds.
Why are latitudes and longitudes called imaginary lines?
Since the Earth is spherical in shape, it is difficult to locate a place on Earth. So our mapmakers devised a system of imaginary lines to form a net or grid on maps and globes Thus there are a number of horizontal and vertical lines drawn on maps and globes to help us locate a place.
What are 2 imaginary lines?
Parallels of latitude and meridians of longitude are the two imaginary lines.
What are the two types of imaginary line?
Two types of imaginary reference lines are used to locate positions or points and to make accurate globes and maps. These lines are called parallels of latitude and meridians of longitude.
What are the 3 types of latitude?
Technically, there are different kinds of latitude—geocentric, astronomical, and geographic (or geodetic)—but there are only minor differences between them. In most common references, geocentric latitude is implied.

Is the imaginary line?
In complex geometry, an imaginary line is a straight line that only contains one real point. It can be proven that this point is the intersection point with the conjugated line. It is a special case of an imaginary curve.
What is an imaginary line which lie on zero degree longitude?
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. 6 – 12+ Earth Science, Geography.
Is prime meridian an imaginary line?
imaginary line around the Earth running north-south, 0 degrees longitude. museum and planetarium in Greenwich, England, that marks the prime meridian and determines Universal Time.
Why are imaginary lines important?
The imaginary line around the globe are very important because are drawn for navigation and geographic information. These lines are helpful in determining location of an object around the globe. Distances of the objects are also found due to these lines.
Is the axis an imaginary line?
The Axis of rotation is an imaginary line passing through the centre of mass of any celestial body around which the celestial body rotates. In case of Earth, the axis of rotation of Earth passes through the north pole, the centre of mass of Earth and the south pole.
What is an imaginary line which lie on 0 degree longitude?
The prime meridian The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth.
What are the 4 main latitudes?
Besides the equator (0°), the North Pole (90°N) and the South Pole (90° S), there are four important parallels of latitudes– (i) Tropic of Cancer (23½° N) in the Northern Hemisphere. (ii) Tropic of Capricorn (23½° S) in the Southern Hemisphere. (iii) Arctic Circle at 66½° north of the equator.
What is 0 degrees longitude called?
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere. 6 – 12+ Earth Science, Geography.
What are the 7 major lines of longitude?
The 7 major lines of latitude are:
- North Pole.
- Arctic Circle.
- Tropic of Cancer.
- Equator.
- Tropic of Capricorn.
- Antarctic circle.
- South Pole.
What are the 7 major lines of latitude called?
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.
What are the 4 different imaginary lines found in the globe map?
Equator, Hemispheres, Axis, and Directions The earth rotates daily about its axis. The north and south poles are the two imaginary points where the axis would enter and exit from the earth if the axis were a pole or a line (see Fig. 1.9).
How many types of imaginary lines are there?
To find positions or points and to create accurate globes and maps, two types of imaginary reference lines are utilised. Parallels of latitude and meridians of longitude are the terms used to describe these lines.
Why is Greenwich meridian called so?
We measure these coordinates as lines of latitude and longitude. The 0° line of longitude starts at the Prime Meridian. It's also called the Greenwich Meridian because it runs through Greenwich, England. Then, we can measure 180° to the west or 180° to the east.
What is the use of Greenwich?
The line in Greenwich represents the historic Prime Meridian of the World – Longitude 0º. Every place on Earth was measured in terms of its distance east or west from this line. The line itself divided the eastern and western hemispheres of the Earth – just as the Equator divides the northern and southern hemispheres.
Which is most famous imaginary line on the Earth’s surface?
Greenwich meridian, also called prime meridian, an imaginary line, last established in 1851, that was used to indicate 0° longitude. It passes through Greenwich, a borough of London, and terminates at the North and South poles. Because it indicated 0° longitude, it was also known as the prime meridian.
What is the use of imaginary lines latitude and longitude?
Latitudes tell us how far north or south from the equator a place is. The semicircles running from North to South on a globe or map are called Lines of Longitudes or meridians. The Prime Meridian is the most important line of longitude. It is located at zero degrees longitude (0˚).
Why is the axis called an imaginary line?
The Axis of rotation is an imaginary line passing through the centre of mass of any celestial body around which the celestial body rotates. … The Earth makes one complete rotation around this imaginary axis every 23 hours 56 minutes 4 seconds. The line passes through the north and south poles of a planet.
Is Equator an imaginary line?
An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere.
