Question

figure 1. cave of crystals (left) and gypsum sand at white sands np (right). although both sites form gypsum crystals, which variable results in a vast difference in the size of crystal? * 1 point
heat
wind
temperature
elevation/location
wind
water source

Explanation:

The size of crystals is highly influenced by the availability of water for crystal - growth processes. Water provides the medium for mineral ions to move and assemble into crystal structures. Adequate and stable water sources can allow for larger crystal formation over time, while limited or fluctuating water availability may result in smaller crystals like the gypsum sand. Temperature, elevation/location, and wind have less direct impact on the fundamental process of crystal - size determination compared to water source.

Answer:

water source
