1. Data Interpretation: Here is a graph showing the gradient of the Nooksack River from the headwaters to the mouth. The graph extends out into the ocean, so the mouth is not on the far-left edge of the graph. The gray area is the land as if we sliced into Earth like a large birthday cake. The locations you looked at are marked. 11a. Describe the general shape of the profile. How does this graph match your observations? Are there places along the profile that appear to differ from the general trend? 1000 m 750 m 600 m 250 m am 1000 m 750 m 250 m Mouth pm Stream Profile of the Nooksack River (Washington State) Source Mouth 120 km 110 km 100 m Mouth Mouth 120 km 310 km 100 w 80 kom Glacial Seciments 11b. The Nooksack River flows across different types of rocks.

11c. Describe what happened to the apparent grain size as you moved downstream. Why might this change take place? 11d. You learned that streams have three zones: Zone 1 - collecting system, Zone 2 transporting system, Zone 3 = dispersing system. Looking over the entire length of the Nooksack River, where are the boundaries between the zones? What evidence supports your claim? CO I payt|| Ten 11e. Explain how the Nooksack River is influenced by the hydrologic cycle. S
