Chapter 8, Using Ratios to Compare
As they move upward, mountain climbers encounter increases in the amount of snow and decreases in the boiling point of water.
Part B, Expressing Change
1. Using the Internet, answer the following question.
a. Find the average annual snowfall in Jackson Hole, Wyoming. Scroll down the page to find your answer.
b. Complete the table.
No. of Years (n ) 1 2 3 4 Total Snowfall (s ) c. Write an equation relating n and s. Name the independent variable.
d. Suppose snow built up on Alaska's Malaspina Glacier at the same rate that it falls in Jackson Hole. Write an equation for the thickness, t, of the glacier, in inches, after y years. Use the minimum thickness given for the glacier. Hint: Be sure to convert the thickness of the glacier into inches.
Part D, Making Connections
2. Using the Internet, answer the following questions.
a. Explain how the boiling point of Water changes in relation to a 5,000 foot change in altitude. Round your answer to the nearest degree.
b. What is the elevation of Butte, MT ? (Enter "Butte" in the first blank. Disregard "to ______".) What is the boiling point of water in Butte?
c. Find the boiling point of water in your town.
d. The equation b = 212 9 (e/5000) expresses the relationship between the boiling point of water, b, and the elevation, e. Use the equation to complete the table.
Elevation (ft) 0 2500 5000 75000 10,000 Boiling point (°F) e. Graph the equation from d.
