Whetpebble Map Reading

Using the Whetpebble map, answer the following questions on area, water flow, elevations, and slope. To calculate slope, measure the rise in elevation divided by the distance on the ground.
1 mile = 1/2 inch

slope = change in elevation (in feet) = ft/mile
distance on ground (in miles)

Example:
slope = 100 feet = 20 ft/mile
5 miles

  1. If you traveled from E to B, what direction are you traveling in?
  2. What is the elevation of A,B,C,D,E, and F? Where is the highest elevation on land? Where is the highest elevation in water?
    1. If I rented a boat at point F, what direction would I float downstream?
    2. After I floated into the Patterson River, which direction would I be traveling then?
    3. Where is my final destination?
  4. What is the change in elevation from Banks Brook to Lake Hopper?
  5. What is the change in elevation from A to B? What is the average rate of change in elevation, or the slope of the land between A and B?
  6. If a raindrop fell at C, what stream would it flow into? At G?
  7. What is the average surface area of Lake Hopper? (Remember: Area= length x width). Give a rough estimate. Answer in square miles.
  8. If the averae depth of Lake Hopper is 20ft, what is the volume of water in Lake Hopper? (Hint: Volume = length x width x depth (height)). Answer in cubic miles.
  9. Calculate the slope between B and D.
  10. What is the area of land you own? (Estimate the area of your square).
