Question

1. the symbolism of frontal lines on weather maps suggests that: fronts are static and unchanging frontal movements are purely random different air masses have distinct boundary characteristics temperature variations are insignificant

Explanation:

Frontal lines on weather - maps represent the boundaries between different air - masses. These air - masses have distinct properties such as temperature, humidity, and density, which create well - defined boundaries. Fronts are not static as they move, and their movements are not random but are influenced by large - scale atmospheric forces. Temperature variations are significant at frontal boundaries.

Answer:

Different air masses have distinct boundary characteristics
