Paired lines of longitude (a line and its partner 180 degrees of longitude away) are great circles. A great circle is a circumference of the planet, whereas a small circle is a circular path (slice of a sphere) that does not circumscribe the sphere.

No, but you're on the right track. A meridian of longitude is only half of a circle,
because it joins the north and south poles. But the circle of which it's a half is
indeed a 'great' one, because its center is at the Earth's center..

Technically, No, but you're on the right track. A meridian of longitude is only half

of a circle, because it joins the north and south poles. But the circle that it's a

half of is indeed a 'great' one, because its center is at the Earth's center.

They're not. Each meridian of longitude starts at one of the earth's poles and ends at the other pole,

so they're semi-circles.

If you take a meridian and hook it up with the meridian exactly 180 degrees away from it, then you have

a great circle. A great circle is any circle on a sphere with its center at the center of the sphere.

No. The equator is a line of latitude. The equator is the only line of latitude that is a great circle.

No. Meridians of constant longitude are semicircles that join the north and south poles. Every one of them crosses the equator.


Lines of longitude are semicircles that extend from the north pole to the south pole?

No. Longitude is east and west of the equator. Lines of Latitude run from the north pole (prime meridian) to the south pole. Try thinking of latitude as the word "ladder" because ladders go up and down. Just a hint ;)
