Station 2:
Use the map of the northwest USA below to answer the following questions. You’ll need a
calculator, and scrap piece of paper or ruler for this. The content of this lab is from previous lab
practicals.

8) How many cm on your ruler is equal to 300km on the map?
3.4 cm
9) Use the scale on the map above to determine the (straight line) distance in km, between the
Owyhee-Humbolt Volcanic field and the Heise volcanic field. There are 1.61 kilometers in 1
mile.
326.48 km
10) What is the rate of movement from Owyhee-Humbolt to Heise. Your answer should be in
km/Ma (kilometers per millions of years). This is the rate of plate movement.
35.105 km/Ma
11) Convert the above answer into cm/yr
3.5105 cm/year
12) Using your cm/y rate, determine how many cm the plate will move in 50 years?
In fifty years, 175.526 cm
13) In which direction is the North American plate moving?
West Southwest
