Question

Determine which of the following summaries of valley formation has taken place in Yellowstone Canyon:

B) The valley is u-shaped, which indicates that a river carved this valley. The valley walls are steepened by stream incision and hillslope processes

D) The valley is v-shaped, which indicates that a river carved this valley. The valley walls are steepened by stream incision and hillslope processes of erosion

A) The valley is v-shaped, which indicates that a glacier carved this valley. The glacier receded and disappeared when the cold period ended, leaving this river valley in its place

Explanation / Answer

ANSWER

THE CORRECT ANSWER IS OPTION D THAT IS THE VALLEY IS V SHAPED WHICH INDICATE THAT A RIVER CARVED THIS VALLEY.THE VALLEY WALLS ARE STEEPENED BY STREAM INCISION AND HILLSLOPE PROCESS OF EROSION.

MANY GEOLOGIST HAVE STUDIED THE FORMATION OF YELLOW STOPNE CANYON AND IT IS SAID THAT THE VALLEY IS FORMED DUE TO THE RIVER FORCE .

THIS IS A TYPICAL EXAMPLE OF V SHAPED VALLEY FORMED DUE TO THE FLASH FLOOD OF THE RIVER AND EROSION (IMMEDIATE AND CATASTOPHIC).

KEN PIERCE ONE OF THE MOST RENOWNED GEOLOGIST HAS FOUND THAT IN THE MOUTH OF THE RIVER THERE WERE ICE DAMS WHICH SLOWLY MELTED AWAY AND CAUSED FLASH FLOODS AND CATASTOPHIC EROSION WHICH RESULTED IN THE FORMATION OF V SHAPED CANYON.

THERE WOULD HAVE BEEN MANY SUCH FLASH FLOODS AND CONTINOUS EROSION WHICH MIGHT HAVE CAUSED THIS NATURAL PHENOMENON..
