Question

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

Explanation:

The terms "cold" and "warm" fronts are relative. In summer, a cold - front is relative to the warmer air masses present in summer. So, a summer cold - front can still have temperatures above 90°F. Fronts can occur in any season, and they are about the relative temperature difference between air masses, not absolute temperature changes.

Answer:

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