Wind Erosion

Authors:
Godfrey Nowlan, GSC
Beverly Ross, Rundle College Junior High School

Materials:

  • Plastic cup
  • Several different kinds of rock
  • White paper

Procedure:

  • Take two pieces of rock and rub them together over a piece of paper for two minutes. Do any particles fall?
  • Explain to students that this is the same as wind erosion. Wind carries tiny particles of sand that blow against other rocks and act as an abrasive to break and wear down rock material.
  • Choose two other kinds of rocks and try the same experiment. Do some types of rock weather more easily than others? How could this explain various landforms?
