Yes, the process of dissolved minerals solidifying to form a crystal is considered a chemical change. This occurs because the minerals undergo a transformation from a dissolved state in solution to a solid crystalline structure, altering their physical and chemical properties. The arrangement of atoms or molecules changes significantly, which is characteristic of a chemical change.

Contrast the formation of minerals from magma and their formations from solution?
The formation of minerals from magma depends on how quickly the magma cools- if it cools slowly the crystals are bigger, slower= smaller crystals. The formation of minerals from solution depends on wether the solution becomes overfilled with a dissolved substance and gets supersaturated, then the individual atoms bond together and mineral crystal is formed from the solution.
Why aren't diamonds made in a laboratory considered minerals?
Lab-grown diamonds have the same chemical composition and crystal structure as natural diamonds, but they are not considered minerals because they are not formed through natural geological processes. Minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure.
What are two main ways that minerals are classified?
Minerals are classified based on their chemical composition and crystal structure. Chemical composition refers to the elements that make up the mineral, while crystal structure refers to the arrangement of atoms in the mineral's crystal lattice.
How are rocks and minarals different?
Rocks are made up of one or more minerals, while minerals are naturally occurring inorganic substances with a specific chemical composition and crystal structure. In other words, rocks are aggregates of minerals, whereas minerals are the building blocks of rocks.
What is an inorganic substance formed in earth with distinct chemical and physical properties?
A mineral is an inorganic substance formed in the Earth with distinct chemical and physical properties. Minerals have a specific chemical composition and a characteristic crystal structure. They can be found in rocks and are essential components of the Earth's crust.
What forms when minerals dissolved in a water solution crystallize?
Non-Clastic, or chemical, sedimentary rock is formed from dissolved minerals. These rocks are made of chemical sediments that have been dissolved from minerals. Solid minerals precipitate out of the solution in water. These minerals layer, and the water above them causes the pressure which forms the rock.
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.
When dissolved in water what will not happen to a salt crystal?
The chemical composition remain unchanged.
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.
Minerals are classified according to their .?
Minerals are classified according to their composition
What are 4 minerals that have iron in their chemical formulas?

What is the significance of the crystal period in the formation of minerals?
The crystal period is significant in mineral formation because it is during this time that minerals grow and develop their characteristic crystal structures. This process helps determine the physical and chemical properties of the minerals, making them unique and identifiable.
Why are not all solids minerals using the word crystal structure?
Not all solids are named minerals because minerals must have a specific chemical composition and crystal structure. While many solid materials have a crystal structure, they may not meet the criteria to be classified as minerals. Minerals must also be naturally occurring and inorganic.
What do minerals not contain?
Minerals do not contain organic matter such as fossils, plants, or animals. Minerals are inorganic solids with a specific chemical composition and crystal structure.
How does crystal precipitation occur in natural environments?
Crystal precipitation in natural environments occurs when dissolved minerals in water become concentrated enough to form solid crystals. This can happen through processes like evaporation, cooling, or chemical reactions. As the water becomes saturated with minerals, the crystals begin to form and grow, eventually settling out of the water and accumulating as solid deposits.
What is the difference between Isomorphic mineral and polymorphism?
Isomorphic minerals have the same chemical composition but different crystal structures, while polymorphism refers to minerals that have the same chemical composition and crystal structure but different crystalline habits. Essentially, isomorphic minerals differ in their arrangement of atoms within the crystal lattice, while polymorphic minerals have the same atomic arrangement but different shapes or forms.
Contrast the formation of minerals from magma and their formations from solution?
The formation of minerals from magma depends on how quickly the magma cools- if it cools slowly the crystals are bigger, slower= smaller crystals. The formation of minerals from solution depends on wether the solution becomes overfilled with a dissolved substance and gets supersaturated, then the individual atoms bond together and mineral crystal is formed from the solution.
