Which propert causes quartz to resist chemical weathering more than any other common mineral?
Weathering is defined as the decomposition of minerals by chemical compounds attacking the crystal structure. Quartz is crystalline SiO2, a compound that is very resistant against all usual aggressive chemical agents (mostly acids in natural environments) and can be decomposed efficiently only by hydrofluoric acid (HF), which rarely occurs in nature. All other common minerals can either be oxidized on the surface (metals and sulphides), dissolved (carbonates and evaporites), transformed into clay minerals (silicates).
What minerals make up a crystal?
By definition, all minerals form crystals. So a crystal can be any mineral.
How does a mineral gets its crystal shape?
minerals get its crystal shape by the heating and pressure from rock
Is tourmaline a mineral or a rock?
Tourmaline is a group of several different minerals that have similar crystal structures, but complex and variable chemical formulas. This gemstone occurs in almost every color.

When minerals form slowly without space restrictions they will develop what?
When minerals solidify they form crystalline structures.
Can lava be a crystal?
Lava itself is not crystalline as it is liquid. Crystals are solid. However, lava can contain crystals of minerals that have started to solidify.
When dissolved in water what will not happen to a salt crystal?
The chemical composition remain unchanged.
Are some crystal formed from minerals dissolved in liquids?
Yes, in fact that's how a lot of crystals are formed.
What are 4 minerals that have iron in their chemical formulas?
crystal galena hernatite lazurite
Minerals with the same chemical formula but different crystal lattice structure are referred to as?
polymorphs
What are minerals considered to be?
A mineral has a fixed chemical composition, and crystal format. Sometimes we may have two minerals with the same chemical formula - e.g. calcite and aragonite, but differ in crystallization.
How many minerals make up rocks?
A mineral is a naturally occurring inorganic solid with a defined chemical composition and crystal structure. There are about 4,000 known minerals.
Which minerals have a crystal shape?
All minerals can be classified into one of a variety of crystal systems.

What characteristiscs do minerals have to have to be a mineral?
Minerals have to have these five characteristics. The five characteristics are solid, crystal structure, chemical composition, made by nature, and inorganic.Those are five characteristics a mineral are required to have to be a mineral.
Do minerals form when a hot water solution cools and the minerals crystallize?
A hydrothermal solution is a very hot mixture of water and dissolved substances. Hydrothermal solutions have temperatures between 1000C and 3000C. When these solutions come into contact with existing materials, chemical reactions occur to form new materials. Also, when such solutions cool, some of the elements in them combine to form such minerals as quarts and pyrite.
