Convection Model Questions 1. Describe what happen to the hot (red) water. 2. Describe what happens to the cold (blue) water. 3. Does the hot water initially rise or sink? Why? 4. To what latitude on the Earth does the hot water bottle correspond? What physical processes cause the air to be hot at that latitude (remember last week’s lab)? Water Vapor Questions 1. At which latitudes do you tend to see dry air (black areas)? 2. At which latitudes do you tend to see moist air (relatively white areas)? 3. At which latitudes does the moisture tend to move from east to west (easterly winds)? 4. At which latitudes does the moisture tend to move from west to east (westerly winds)? For descriptions of rocks refer to the chapter on Weather in the course module, OER textbook, or lecture textbook.
