Quick Check (pg. 281) -Compare and Contrast: How does what low and high pressure systems tell you differ from what warm and cold fronts tell you? a) Warm and Cold fronts tell you weather is approaching. Low pressure signals warmer air and high pressure signals colder air. Earth’s Weather: Lesson 5
