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.
What are the 3 imaginary lines around the Earth called?
Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude.
What is the name of the imaginary line that divides the Earth in half?
The Equator The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.
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.
What are the types of imaginary line?
It divides the northern and southern hemispheres and exhibits distinct physical characteristics due to its unique gravitational pull.

What are the four imaginary lines on the globe?
Four of the most significant imaginary lines running across the surface of Earth are the equator, the Tropic of Cancer, the Tropic of Capricorn, and the prime meridian.
Is Equator an imaginary line?
A circle of latitude is an imaginary ring linking all points sharing a parallel. The Equator is the line of 0 degrees latitude. Each parallel measures one degree north or south of the Equator, with 90 degrees north of the Equator and 90 degrees south of the Equator.
Is orbit an imaginary line?
Orbit: The imaginary line on which the earth moves around the sun is called its orbit.
What are the two imaginary lines of the Earth?
These lines are called parallels of latitude and meridians of longitude. Two of these imaginary reference lines, the equator and the prime meridian, are called primary reference lines because they are where we start the numbering system.
What are 2 imaginary lines?
Parallels of latitude and meridians of longitude are the two imaginary lines.
Why is 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.
What is the name of the imaginary line that divides the Earth into Northern and Southern Hemisphere?
The equator The equator is the most well known parallel. At 0 degrees latitude, it equally divides the Earth into the Northern and Southern hemispheres. From the equator, latitude increases as you travel north or south, reaching 90 degrees at each pole.
How many imaginary lines are there?
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. A circle of latitude is an imaginary ring linking all points sharing a parallel. The Equator is the line of 0 degrees latitude.

What is the name of the imaginary line that passes through the North Pole and the South Pole?
meridian. one of the imaginary lines that goes around the Earth from the North Pole to the South Pole.
What are longitudes 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. The prime meridian, which runs through Greenwich, England, has a longitude of 0 degrees.
Where is the meridian line?
Greenwich What is the meridian line? The meridian line in Greenwich represents the Prime Meridian of the world, Longitude Zero (0° 0' 0"). Every place on the Earth is measured in terms of its angle east or west from this line. Since 1884, the Prime Meridian has served as the reference point for Greenwich Mean Time (GMT).
