Facts about Crystals
A crystal is a solid figure composed of a repeating pattern of geometric shapes. When a liquid cools and hardens, crystals form. The molecules in the liquid pull together in a pattern during the crystallization process. When magma cools slowly, some crystals, such as emeralds, form.
Crystals include diamonds and rubies.
Snowflakes that form in clouds are considered ice crystals.
In quartz watches, crystals serve as the mechanism that keeps the watch accurate in time.
When water evaporates from a saltwater mixture, salt crystals form.
Rectangles, triangles, and squares are just a few of the shapes that can form in a crystal.
The elements and chemical bonds that make up a crystal determine its shape.
A crystallographer is someone who studies crystals.
Crystals can be formed by some living organisms.
Many people believe that crystals have healing properties because they can stimulate the body’s energy.
Although crystals are usually formed naturally, they can also be created in a laboratory under controlled conditions by scientists.
Crystals not only have sharp edges, but they also have flat faces known as facets.
Bedrock is composed of crystals in high concentrations.
Most solids can only form one type of crystal, but some can produce multiple crystal forms.
Almost all crystals have some type of flaw in which the shape pattern is distorted.
Crystals are classified into four types: covalent, metallic, molecular, and ionic.
