Earth Science: Stream Erosion
by Texas Instruments - Simulation Lesson


  • Students will recognize the difference between erosion and deposition.
  • Students will understand the relationship between the slope of a watershed and the rates of runoff, erosion, and deposition.


  • erosion
  • deposition
  • flow rate
  • slope

About the Lesson

In this lesson, students will manipulate the slope of the surface over which the water is flowing to show varying rates of erosion and deposition. Note: Students should use the TI-Nspire computer software or TI-Nspire™ Apps for iPad® for an optimal experience with this lesson.

As as result, students will have a better understanding of:

  • how slope affects flow rate.
  • how flow rate affects erosion and deposition in a stream.
