A ray of light has an angle of incidence of 27.0 ° on a block of quartz and an angle of refraction of 18.5°. What is the index of refraction for this block of quartz?
Quartz is a mineral that can form a part of all three rock types. Quartz is a fairly common mineral, one of the most common of all minerals in the near surface of the earth. Whether you would term a rock sample containing quartz (or consisting entirely of quartz) as igneous, metamorphic, or sedimentary is very much dependant on the situation. If you are classifying the type of environment where the mineral is found, you must include all three as possibilities.
Quartz is not a rock; it is a mineral. I believe the formula is SiO2.
quartz is a mineral and is abundant in igneous, metamorphic and sedimentary rocks. in felsic igneous rocks quartz is common.
All of the above. Quartz is a mineral, SiO2, and can be found in considerable amounts in all of the rock types. Eg: Sedimentary: sandstone (can be 100% Quartz) Igenous: granite (normally around 60% Quartz) Metamorphic: quartzite (metamorphosed sandstone, 100% Quartz)
Quartz is a hard crystalline mineral which is found abundantly all over the Earth in a variety of forms. It is the most common mineral on Earth, making up 12% of the Earth's crust by volume, and is used in a wide variety of applications including jewelry, scientific research, manufacturing, and building. Because of its many uses, quartz is also a very important mineral, and some rare varieties of quartz are considered to be quite valuable. It can also be quite beautiful, especially when cut and polished by a jeweler who appreciates the properties of quartz. It is often used as a cheaper substitute for fancier gems, and when handled well, it can be difficult to distinguish from more expensive counterparts.
