What is the imaginary circle on Earth called?
The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres.

Earth is surrounded by invisible gases that form a thin protective blanket that we call the atmosphere.
What is the name of the imaginary circle around the middle of the Earth that separates the northern and Southern hemispheres?
The Equator
The Equator, or line of 0 degrees latitude, divides the Earth into the Northern and Southern hemispheres.
What are the 3 imaginary lines around the Earth called?
The imaginary lines circling the globe in an east-west direction are called the lines of latitude (or parallels, as they are parallel to the equator). They are used to measure distances north and south of the equator. The lines circling the globe in a north-south direction are called lines of longitude (or meridians).
Why is equator called the great circle?
A Great Circle is any circle that circumnavigates the Earth and passes through the center of the Earth. A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles.
Is there a invisible shield around Earth?
An invisible shield has been discovered some 7,200 miles above Earth that blocks so-called ‘killer electrons,’ which whip around the planet at near-light speed and have been known to threaten astronauts, fry satellites and degrade space systems during intense solar storms.
What country is in the middle of the earth?
Which country is at the centre of the world? Ghana is geographically closer to the “centre” of the Earth geographical coordinates than any other country even though the notional centre (0° 0°) is located in the Atlantic Ocean approximately 614 km (382 mi) off the south-east coast of Ghana on the Gulf of Guinea.

What is the other name of great circle?

What is the biggest circle?
The equator is the circle that is equidistant from the North Pole and South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only ‘great circle’ (a circle on the surface of the Earth, centered on Earth’s center).
What is known zero meridian?
The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth.
Is there a net around the Earth?
In 2017, NASA space probes detected a massive, human-made ‘barrier’ surrounding Earth. And tests have confirmed that it’s actually having an effect on space weather far beyond our planet’s atmosphere.
What are killer electrons?
Killer electrons are what scientists call the electrons trapped in Earth’s outer radiation belt that can damage or “kill” satellites. Many satellites that have flown through the Van Allen radiation belts have confirmed their existence and measured them. Killer electrons have been blamed for many spacecraft failures.
Is Kaaba the Centre of the Earth?
Armstrong further says that the Kaaba was thought to be at the center of the world, with the Gate of Heaven directly above it.
Which is the hottest part of the Earth?
