Answer 1

Answer:

(1)answer. Important lines of longitude

Longitude is the measurement east or west of the prime meridian. Longitude is measured by imaginary lines that run around the Earth vertically (up and down) and meet at the North and South Poles. These lines are known as meridians. Each meridian measures one arcdegree of longitude.

(2)answer.the Equator

A great circle always divides the Earth in half, thus the Equator is a great circle (but no other latitudes) and all lines of longitude are great circles. The shortest distance between any two points on the Earth lies along a great circle.
