A - Wind Speed on Lake Erie

Click here to go to the LAKE ERIE WIND SPEED site.

1. Predict which areas of Lake Erie will have the highest waves. 
2. Record your answer as a written description of the location relative to other parts of the lake.
3. Draw the area of highest waves on the map of Lake Erie. Why do you think these areas will have the highest waves?
4. Convert the highest wind speed from knots to miles per hour. (One knot is 1.15 miles per hour.)

B - Wave Height on Lake Erie

Click here to go to the LAKE ERIE WAVE HEIGHT site.

1. Check your prediction in #1 in part A above.  Was your prediction correct?
2. How many feet high are the highest waves on Lake Erie?

C - Water Surface Elevation

Click here to go to the LAKE ERIE WATER SURFACE ELEVATION site.

• This map uses elevation like a topographic map. "Elevation" means height above sea level.  Higher elevations are higher above sea level.

1. What part of Lake Erie has the highest water elevation?
2. What part of Lake Erie has the lowest water elevation?
3. What is the direction of water flow in Lake Erie?
4. What is the total difference in water elevation from the northeast end of Lake Erie to the southwest end?
