A snow crystal appears when water vapor in the air converts directly into ice without first becoming liquid water. ... The exact shape of the final snow crystal is determined by the precise path it took through the clouds. But the six arms all took the same path, and so each experienced the same changes at the same times.
I assume the mountainous area.
Explanation: Hydroponic describes planting without soil. When there is erosion on a mountain area, any soil or dirt would likely go away.
Hope this helps!
