4.  Use these values to calculate the gradient (i.e., slope = rise/run) of the river channel between these two points in m/km and degrees . Note: To calculate slope in degrees you have to first standardize the units  that you will be using and then divide the rise over the run. The resulting number is the tangent of the slope. To find the slope in degrees you will have to find the inverse tangent of your number. Think SOH CAH TOA ! (tanθ = opposite/adjacent)  (2 marks)

Gradient (m/km and degrees):                                          

                                                        

5. Using Google Earth, make two placemarks with the “add placemark” tool in UTM Zone 20T at (Placemark 1: 356592.20 m E, 5057241.56 m N) and (Placemark 2: 362911.55 m E, 5053189.11 m N).  Now create a path between the two placemarks using the “add path” tool, from Placemark 1 to Placemark 2, name it, and then click OK.  Now right click on the path and choose “Show elevation profile” from the menu.  By running your cursor along the profile, it will give you spot elevations and distance, along with an arrow showing your position on the map.  Use this tool to answer the following questions (17 marks).

i)    What are the elevations at these profile distances?  0 km, 2.05 km, 5.89 km, 6.7 km and 7.29 km.

ii)  At what distances does Route #114 and Route #915 cross the profile?

iii)  Given the Bay of Fundy tides rise at least 5m above mean sea level in this area of the bay, what areas are frequently flooded with sea water?  Provide distance measurments along the profile as answers (i.e., from XX km to XX km, at XX km, etc.).

iv)  Finally, report the total distance of the profile, along with the total elevation gain and loss of the profile.

i) What are the elevations at the following distances along the profile?

0 km: _____________________________________

2.05 km: ­­­­­­­­­­­­­­­­­­___________________________________

5.89 km: ___________________________________

6.7 km: ____________________________________

7.29 km: ___________________________________

ii) At what distances do the roads cross the profile?

Route #114: _________________________________

Route #915: _________________________________

iii) What areas along the profile are frequently flooded with sea water?

________________________________________________________________

­­­­­­­­­­­­­­­­­­­­­­­­________________________________________________________________

iv) What is the total distance of the profile, as well as the elevation gain and loss?

Total distance: ­_______________________________

Elevation gain/loss: ___________________________
