Question 4 • Earth and Space Science

How does the process of crystal growth explain the difference between natural and synthetic specimens?

Answer
A
Natural crystal growth allows crystals to cool very slowly, leading to uniform crystals, while synthetic growth happens quickly under controlled environments.
B
Natural crystal growth forms under identical conditions worldwide, leading to uniform crystals, while synthetic growth forms under conditions with frequent disruptions.
C
Natural crystal growth occurs in changing environments, causing irregularities, while synthetic growth occurs under stable conditions that produce uniformity.
D
Natural crystal growth occurs in stable environments, producing uniformity, while synthetic growth occurs in unstable environments that create irregularities.

Explanation

Natural crystals form over time in geological environments where temperature, pressure, and the supply of materials can change. Those changing conditions can create irregularities in the crystals. Synthetic crystals are grown under controlled, stable conditions, which tend to make them more uniform, so choice C is correct.
