Fronts
Describe cold, warm, and stationary fronts and their map symbols.
Warm-up, learn, try it together, practice, then a quick check. About 15 minutes.
What children learn in Level 33
- Huge bodies of air sit over the land, some warm and some cold. Where two of them meet is called a front. Most weather changes happen at fronts.
- At a cold front, cold air pushes in fast. Storms often form, and then it gets cooler. Maps show it with blue triangles, pointing the way it's moving.
- At a warm front, warm air slides in slowly. Steady rain often falls, and then it gets warmer. Maps show it with red half circles.
- At a stationary front, neither side is moving ahead, so the same weather lingers. Maps show both symbols, on opposite sides of the line.
Georgia Standards of Excellence in Science:
- S4E4.b — Interpret data from weather maps, including fronts (warm, cold, and stationary), temperature, pressure, and precipitation to make an informed prediction about tomorrow's weather.
