Why are crystals rare?
Answers
Answer:
The Correct Answer is mentioned below
Explanation:
Erosion and mixed composition are the two answers. Here on Earth, wind, rain, and water flow have a way of knocking and mixing things around. This erosion breaks down large crystals, such as a palm-sized amethyst, into smaller crystals. Sand, silt, and clay are the end products. Because of erosion, the earth's surface is covered with sand, silt, and clay rather than huge gem-quality crystals. A mixed composition also means that when rocks grow inside the ground, crystals of one substance get in the way of crystals of another material as they form.
As a result, the crystals are tiny in size. Solid granite, for example, is made up of tiny quartz, mica, and feldspar crystals. Individual crystals are visible as flecks of grains in granite.
