What is silica made out of?
Silica is seen commonly in nature as sandstone, silica sand or quartzite. It is one of the most abundant oxide materials in the earth's crust. There are three crystalline forms of silica: quartz, tridymite, and cristobalite.

Is volcanic ash air pollution?
Yes. Volcanic ash falls into the air pollutant category of particulate matter. It can cause respiratory and eye symptoms during and after ash fall. The ash contains the minerals quartz, cristobalite, or tridymite. These are free crystalline silica which may cause silicosis which is a disabling and potential fatal lung disease. The recommended respirable exposure limit of 50 ug/m3 of particulate in air can be exceeded for short periods of time.

How many types of silica are there?
Silica, primarily composed of silicon dioxide (SiO2), exists in several forms, with the two main types being crystalline silica and amorphous silica. Crystalline silica includes varieties like quartz, tridymite, and cristobalite, while amorphous silica is found in forms such as opal and siliceous earth. Additionally, silica can be categorized based on its occurrence and structure, leading to various industrial and natural types. Overall, there are numerous specific forms of silica, but they generally fall under these broad categories.

What is an example of Polymorphism?
A polymorph is defined as same composition, different chemical structures. Quartz, cristobalite, and tridymite are examples of polymorph because they are three different minerals with the same chemical composition. Graphite and diamond are also good examples of polymorphism. They both contain carbon atoms, but they have extremely different properties because of the condition in which they formed. Diamond forms where extreme pressures and temperatures produce its compact structure. On the other hand, graphite forms under comparatively low pressures and it has weekly bonded carbon sheets that create its greasy feel. The difference in conditions makes diamond much harder than graphite and graphite much more useful as a lubricant.
Are quartz and feldspar examples of polymorphs?
No, they are examples of silicate minerals. However, quartz is the collective name for a bunch of SiO2-polymorphs, like tridymite, coesite, alpha-quartz and beta-quartz. Likewise, K-feldspar is the collective name for the KAlSi3O8-polymorphs microcline, orthoclase and sanidine. Polymorphs are chemically identical, but differ in the crystallographic structure. To confuse it, each polymorph mentioned above is also a mineral ...
What is silica dust?
Crystalline silica is a basic component of soil, sand, granite, and many other minerals. Quartz is the most common form of crystalline silica. Cristobalite and tridymite are two other forms of crystalline silica. All three forms may become respirable size particles when workers chip, cut, drill, or grind objects that contain crystalline silica.
