3. Guided Practice Work with your table 10 minutes to answer 12 questions Talking quietly with partners We will be discussing the answers afterwards You will be expected to answer http://www.youtube.com/watch?v=vPC5i6w3yDI

4. Guided Practice 1.Why does warm air rise at a front? Warm air is less dense = rises 2. Why does cold air stay close to the ground? Cold air is more dense = sinks

5. 3. What are the first signs of an approaching warm front? Light rain or light winter precipitation and fog 4. What are the first signs of an approaching cold front? precipitation

6. Guided Practice 5. a. What type of weather is associated with a cold front? Thunderstorms, heavy rain then clear skies with lower temperatures and lower humidity b. What type of weather is associated with a warm front? Light rain then clear skies with higher temperatures & high humidity

7. Guided Practice 6. List two ways cold and warms fronts are similar or related to each other: (a)Associated with Rain and Clouds (b) Move from west to east

8. 7. Which front moves through an area faster? Why? Cold because warm air is easy to push (lighter & less dense) Which front moves through an area slower? Why? Warm air cannot move cold air because it is heavy & more dense so eventually the warm air rises above the cold air mass

9. 8. If a warm front occurs in the winter, what type of snowstorm would it likely bring? Light snow & long duration 9. If a cold front occurs in the winter, what type of snowstorm would it likely bring? A lot of snow because cold air pushes the warm & moist air up, which causes it to condense & create precipitation

10. 10. Which type of front would likely bring hail and possible tornadoes into an area? How do you know? Occluded Front Warm air is wedged together by cold air.
