Fronts are boundaries between air masses of different temperatures and humidity levels (e.g., between warm and cold air masses). Warm air rises as cool air moves in to take its place, causing a front between the two different air masses.

Question

Which of the following can be expected at such fronts?
A.
clouds and precipitation
B.
dry weather
C.
clear skies
D.
fog

Answer 1

At fronts where warm air rises over cooler air, you can typically expect:

A. clouds and precipitation

This occurs because the rising warm air cools and condenses, leading to the formation of clouds and possibly precipitation. The other options (B, C, and D) are less likely to occur at fronts.
