Part 2: Surface Air Pressure Map

Follow the directions on the webpage to color code your map and then use your map to answer the following questions. Make a key for your map to explain what the different colors and symbols represent.

KEY:
  1. What type of lines connect points of equal air pressure on the map above? ______
  2. In what areas do you expect clear skies and nice weather? In what regions do you expect rain? Explain your reasoning.
  1. How can you tell which area on the map will have the fastest winds? Place a star where the winds are the fastest and include this in your key.
  1. How can you tell which area on the map will have the slowest winds? Place a circle on the map where the winds are the slowest and include this in your key.
  1. Based on the pressure gradient alone, would you expect the winds to blow from East to West, or West to East?
  1. The pressure gradient is the major force that gets winds moving, what are the 2 other factors that control winds?
  1. Because of these other factors, winds in the northern hemisphere that would go straight actually curve to the ______.
  2. What is the name of the tool that is used to measure air pressure?

Part 3: Surface Temperature Map

KEY:

Follow the directions on the webpage to color code your map and then use your map to answer the following questions. Make a key for your map to explain what the different colors and symbols represent.

  1. What type of lines connect points of equal temperature on a weather map?
  1. If Earth’s axis wasn’t tilted, and the surface was uniform, there lines would run straight East to West because ______is the most important temperature control.
  1. Describe how each of the 5 other temperature controls we discussed in class work.
  1. Put a large “C” on the coldest region of the map and include it in your key. Using at least 2 of the temperature controls listed above, give a hypothesis for why this region is colder than the rest.
  1. Put a large “H” on the warmest region of the map and include it in your key. Using at least 2 of the temperature controls listed above, give a hypothesis for why this region is warmer than the rest.
