Question

1. the relative nature of \cold\ and \warm\ fronts means that: fronts always indicate absolute temperature changes a \cold front\ in summer could still involve temperatures above 90°f fronts only occur in winter conditions temperature differences are always greater than 20°f

Explanation:

The terms "cold" and "warm" fronts are relative to the air masses they are replacing. In summer, a cold - front can still bring relatively high temperatures compared to winter but is cooler than the air it is displacing. Fronts don't always indicate absolute temperature changes, occur only in winter, or have temperature differences always greater than 20°F.

Answer:

B. A "cold front" in summer could still involve temperatures above 90°F
