Listed following are the latitudes of several locations on Earth. Rank these latitudes from left to right based on the maximum altitude (on the meridian) at which the celestial equator passes through the local sky, from lowest altitude (nearest the horizon) to highest altitude (farthest above the horizon).
a. latitude 70 degrees N
b. latitude 40 degrees N
c. latitude 50 degrees N
d. latitude 10 degrees N
e. latitude 30 degrees N
