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) the Aleutians Islands
2) the Big Island of Hawaii
3) the Grand Canyon
4) the Sierra Nevada Mountains

"the socialist system that had been in place had brought economic ruin to the country." i hope this !

No map. ie where is the map as this question cannot he answered without a map so the question as is is irrelevant and i am disappointed as i am a geologist.

As someone who have lived in northern moravia at industrial steel and coal city of ostrava, the closest point is b), but it is questionable. i am not sure how to compare efficiency of largest steel mill in czech republic in comparison to china which is the biggest exporter, but czech steel factories were modernized and run more efficient that 25-35 years ago, and been privatized and owned by mittal. the workforce had been shrinking, so not exactly sure what that c is pointing to (aging of workforce, size of it, or quality). northern moravia is a part of larger coal basin that extend to poland with large coal deposits. this was foundation for the steel industry in the 1800's together with large ore deposits that was mined in proximity of the beskidy mountains less than 25 miles from ostrava. the iron ore mines had been depleted for several decades, and since the late 70's when communists run the country, they were already importing soviet iron ore. coal mining within city of ostrava cased to exist in the 1990's due environmental issues, and also cost. the mines were getting deeper and more costly to operate and there is no more mining within ostrava. couple mines are still in operation in karvina county which is next to ostrava. currently the coal deposits south of the city were not opened due environmental issue which would mean destruction of third largest mountain range in the country. therefore, my conclusion is is b, as the ore and coal resources been shrinking. the biggest challenge not mentioned here is of course competition from russia, ukraine, and china, which can produce steel much cheaper.
