Question

question 12 (multiple choice worth 1 points) tg.04 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 students experiment? the aleutians islands the big island of hawaii the grand canyon the sierra nevada mountains

Explanation:

1. Analyze the experiment: The experiment involves pushing both ends of a straw towards the middle (clip), causing it to snap and bend upward, simulating compressional stress and folding/faulting (mountain - building from convergent plate boundaries or crustal compression).
2. Analyze each option:

• Aleutians Islands: Formed by subduction (ocean - ocean convergent), not the compressional folding/faulting shown in the experiment.
• Big Island of Hawaii: Formed by hot - spot volcanism, not related to the stress in the experiment.
• Grand Canyon: Formed by erosion (river - related), not by the compressional process in the experiment.
• Sierra Nevada Mountains: Formed by tectonic uplift and compressional forces (related to crustal compression, similar to the straw being pushed and deforming), matching the experiment's demonstration of compressional stress leading to upward deformation.

Answer:

D. the Sierra Nevada Mountains
