There is no specific reason for it, it is just an occurrence of nature.
because nothing in nature is flawless, crystals either grow from minerals or form under lots of pressure and heat
Yes. Salts can form crystals (salt crystals).
Crystals of the same substance form a similar structure in nature, but there are many basic crystaline structures in different substances
A natural form is when something grows or developes in nature. for example crystals are natural forms because they are formed only in nature.
There is no single answer for this. Many chemicals form crystals, and the chemical determines the nature of the crystal. If you know what kind of crystal, then you know its chemical nature. For example, common clear quartz crystals are made up of SiO2 or Silicon dioxide. Copper sulfate crystals have an entirely different shape and a deep blue-green color, and both are different from crystals of common table salt.
a saturated solution will form crystals
When magma coos slowly, it allows large crystals to form. The process of evaporation helps to form crystals.
Gatorade will form crystals faster because it contains electrolytes, which are a form of salt. Salts are crystals, thus your answer. Pure water will not form crystals at all unless it reacts with another substance.
Most minerals form crystals.
Most minerals form crystals.
Table salt is made of many tiny crystals. When you mix these salt crystals with water, they dissolve, losing their crystalline form. When the water evaporates, the salt crystals form once again.
It is unusual for crystals to form on paper clips. Possibly if you use them to stir your coffee you might get sugar crystals.
