Question

select the statement regarding location reference systems that is not correct. the equator is the only line of latitude that forms a great circle. lines of latitude parallel each other. lines of longitude all intersect at the equator. lines of longitude are all great circles.

Explanation:

1. Analyze the first option: The equator is a great circle (divides Earth into two equal hemispheres), and other latitudes are small circles, so this is correct.
2. Analyze the second option: Lines of latitude (parallels) are parallel to each other, which is a basic property, so this is correct.
3. Analyze the third option: Lines of longitude (meridians) intersect at the poles (North and South Poles), not at the equator. So this statement is incorrect.
4. Analyze the fourth option: Each line of longitude is a great circle as it passes through the poles and divides Earth into two equal hemispheres, so this is correct.

Answer:

C. Lines of longitude all intersect at the equator.
