Warm-Up Please write down these questions and leave space to answer them. (Do not answer them yet) 1. What is the main cause of air movement in the atmosphere? 2. What is a convection cell? 3. Describe the movement and air pressure associated with warm and cold air. 4. What and where is the Jet Stream? 5. In which directions does air curve due to the Coriolis Effect?
RED SLIDE: These are notes that are very important and should be recorded in your science journal. BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly. Copyright 2010 Ryan P. Murphy

Answer! A band of high pressure systems exist south of the equator. Copyright 2010 Ryan P. Murphy
Answer! They also exist just north of the equator. Copyright 2010 Ryan P. Murphy
Answer! Low pressure systems exist below the high pressure systems. Copyright 2010 Ryan P. Murphy
Answer! Low Pressure system exist at the mid latitudes. Copyright 2010 Ryan P. Murphy

All Fronts are caused by air pressure. Copyright 2010 Ryan P. Murphy
Remember: Cold sinks, warm rises
Cold Front: Form where cold air moves towards warm air. Creates rain storms. Copyright 2010 Ryan P. Murphy
