Final answer:
The statement is true: snow lines occur at lower elevations as latitude increases because colder conditions are encountered more quickly with less vertical distance from sea level as one moves away from the equator toward the poles.
Step-by-step explanation:
The statement that snow lines generally occur at lower elevations with increasing latitude is true. Snow lines refer to the lowest elevation at which snow remains on the ground throughout the year. As latitude increases, temperature decreases, which is a result of a latitudinal cline. This causes snow lines to appear at lower elevations because colder conditions are reached with less vertical distance from sea level.
Furthermore, the phenomenon of permanent snow cover at the summit of high mountains near the equator transitioning into various climates as elevation decreases is a clear indication that snow lines are indeed influenced by both latitude and altitude. Hence, the pattern that you see is that as you move away from the equator, towards the poles, the altitude at which snow persists year-round decreases.
