One student designed an experiment to demonstrate the formation of a geologic feature. The steps of the experiment are listed below. Place a rectangular piece of cardboard on a table. Take a two inches long rigid broom straw. Place the straw on the cardboard along one of its edges. Use a clip to attach the middle of the straw to the cardboard so that approximately half of the straw is on each side of the clip. Place one hand on each of the two halves of the straw. Push both ends of the straw towards the clip. Observe the straw snap as it moves up and bends due to pressure. Which of these geologic features was created by the process demonstrated by the student's experiment? (1 point)
