Experiment 69. Sedimentation. 



Apparatus: Student lamp chimney with stoppers to fit 

 both ends. 



Materials: Coarse gravel, sand, loam, and clay. 



a. Mix equal parts of the materials to make enough to fill 

 the chimney two thirds full. Fill rest of the space with water. 

 Then stopper and shake vigorously. Allow the chimney to 

 stand in an upright position until the water becomes clear. 

 Describe the arrangement of the materials. Stratified rock 

 was formed by the transportation of different materials in 

 water, and the sedimentation, while slower, was similar to 

 that which took place in the lamp chimney.
