Why is a great circle used for navigation?
Because any 'Great Circle' is the shortest distance across a sphere. Where the Earth is concerned , all the meridians and the Equator are Great Circles. The Plane of a 'Great Circles ' 'cut' the sphere into two equally sized hemispheres. NB Other than the Equator all the latitudes are NOT great Circles.
What parallels are not circles?
If two circles are drawn using the same centre, the two lines of the circles are parallel as they don't meet each other.Two straight lines (think of railway tracks) are drawn next to each other, but never meet, they are parallel lines.
Why does Pi work for all circles?
Because all circles are similar.
Are all parallels equal?
Yes of course!
Why are lines of longitude called great circles?
Because they make big circles around the Earth.
Which parallel of latitude are great circles?
All parallels of latitude, except for the Equator, are not great circles. Great circles are the largest circles that can be drawn on a sphere and pass through its center, whereas small circles do not pass through the center of the sphere.
Is latitude and parallels related?
Circles of latitude are also know as parallels.
Are circles of latitude and parallels of latitude the same?
Yes.
What parallel lines split the world?
"Parallels" or "Circles of Latitude".
Which parallels are not circles?
a cylinder
Why all meridians of longitude are semi-great-circles?
-- Each meridian joins the north and south poles, making it a semi-circle. -- The center of the circle of which it is a semi is at the center of the Earth, making it a 'great' one. Among parallels of latitude, only the equator is a great circle.
Why is the equator the only parallel that is a great circle?
The equator is the only parallel that is a great circle because it is centered on the Earth's axis of rotation. This means that it divides the Earth into two equal hemispheres and its circumference is the maximum possible for a circle on the Earth's surface. Other parallels are smaller circles and not great circles.
Parallels are imaginary circles around the globe that measures what?
Parallels are imaginary circles around the globe that measure latitude, which is the distance north or south of the equator. They help in locating positions on the Earth's surface and are often used as reference points in navigation and mapping.
Is another name for a line of latitude?
Linesof latitude are also known as circles of latitude or parallels.

What is a another name for latitude lines?
They are sometimes called parallels. They are parallel to the equator, zero degrees latitude, and parallel to each other. They are all circles, except for the poles which are points.A parallel is another name for a line of latitude because all lines of latitude are parallel to each other.Graticule .parallels
What is River partially parallels the Great Wall?
