उत्तर
except for the equator, other parallels of latitudes are not great circles this is happening because other parallels of latitudes (which are small circle) do not lie on the plane passing through the center of Earth /globe nor do they divide the earth/globe into two equal halves, which the only equator can do. This equator is the only latitude which is a great circle and all other latitudes are small circles.
