The Greenwich Meridian is an imaginary longitude line running round the earth North, South, North at 0 degrees in the same way that the Equator is an imaginary latitude line running round the earth.
I do not care in the freaking slightest
It is called a great circle and the plane that circle makes must pass through the geometric center of the globe. The largest circle that can be drawn round the Earth is the great circle round its middle, the "equator" this is because the spinning of the earth makes it 'fatter' round the middle.
because when the earth was made the big bang wanted it to bee round
An imaginary line which runs round the globe, called the "equator".
because earth is also round
round, as in the shape of a circle or earth
The earth is approximately a sphere (round like a ball). From any direction, its outline will be a circle.
The reason is because it is in the middle of the earth so it makes the biggest, most round circle, (around the Earth). it has the farthest to go around thus creating a perfectly round circle of latitude around Earth........................(i'm 13)
Possibly you mean The Equator, which is the imaginary line which runs round the Earth halfway between the poles.
a circle, because there is no air in space, and Earth is round so, air is round too.
it's round like a circle. It's the shape our earth is in.
