SUPERPOSED STREAMS
This page is for students in the Geology 1 and Geology 4 classes.
The image on this web page is a scan of the paragraph on Superposed Streams from your textbook, Physical Geology.
It was last published on the 10th edition, even if we are currently using the 12th edition.
The subject has been discussed in class, so I am providing you with textbook materials from the older edition.

Fig. 10.45 - Development of a superposed stream
(A) Stream initially cuts through the horizontal sediment
(B) Continued erosion removes horizontal strata, and stream cuts through underlying rock,
forming narrow valleys in resistant rocks.
