• We will watch the video two times. Listen for
answers to your questions as we watch it the

Cold Front
Sketch the diagram of the cold front (the one on
top). Include temperatures, arrows showing
the direction of movement and the line with
triangles pointing toward the warmer air.
Warm Fronts
• Do the same for the warm front.
Stationary Front
• A cold front is the boundary between cool and
warm air when the cool air is replacing the
warm air. A warm front is the boundary when
the warm air is winning the battle. When the
pushing is a standoff, the boundary is known
as a stationary front. Stationary fronts often
bring several days of cloudy, wet weather that
can last a week or more.
