52. Station 17
Bryce Canyon is not a “real” canyon. It is notcarved by flowing water. For 200 days a yearthe temperature goes above and below freezingevery day. During the day, melt water seeps intofractures only to freeze at night, expanding by9%. This is an example of (physical orchemical) weathering. In addition, rainwater, whichis naturally acidic, slowly dissolves the limestone,rounding off edges and washing away debris. Thisis an example of weathering.
