10.6C| In-Person Stream Landforms Lab

For this exercise, you'll apply what you've learned about reading and interpreting topographic maps to interpreting streams and stream-related landforms on topographic maps. 

Instructions 

1. Save a copy of the  Stream Landforms Lab. You'll record your answers on this copy. 
2. Read the first page of the lab carefully to remind yourself of the information essential for this lab. 
3. The pre-lab questions contain essential vocabulary and hyperlinks. These will be very useful for completing the lab.  
4. Collect each topographic map as instructed under "In-class activities". Answer all questions.
5. For questions where you're asked to draw or calculate do this work on a separate sheet of paper. You will embed an image of this work for credit. 
6. Paste a link to your saved copy of the lab as directed.
7. Embed images of your work as directed.  

You have two attempts to embed your drawings and no time limit.  

Time Needed 

About 90 minutes to 2 hours. 

Learning Objectives

• Students can describe the role weathering, mass wasting, and erosion play in shaping Earth's surface and can provide and/or identify examples of each of these processes
• Students can differentiate between constructive and destructive geologic processes, are able to explain the energy driving these processes, and can identify examples of each
• Use topographic maps to identify stream-related landforms and make interpretations of geologic processes
• Calculate the gradient of a stream  
• Compare and contrast the physical characteristics of the three types of stream channels and locate each along a typical stream profile
• Describe the relationship between sinuosity, valley width/channel width ratio, and gradient
