Here is the information I found based on your search:

  • Rock: In geology, rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter. Rocks are composed primarily of grains of minerals, which are crystalline solids formed from atoms chemically bonded into an orderly structure. Some rocks also contain mineraloids, which are rigid, mineral-like substances, such as volcanic glass, that lack crystalline structure. The types and abundance of minerals in a rock are determined by the manner in which it was formed. Rocks are classified according to characteristics such as mineral and chemical composition, permeability, texture of the constituent particles, and particle size. These physical properties are the result of the processes that formed the rocks. Over the course of time, rocks can be transformed from one type into another, as described by a geological model called the rock cycle. This transformation produces three general classes of rock: igneous, sedimentary, and metamorphic).

  • Minerals: Minerals are solid substances that have formed naturally in the Earth. They have a characteristic chemical and physical properties and usually a regular crystal structure. Most rocks that we see today are made of minerals (they are the ingredients in rocks) and both precious metals and gems are subsets of minerals. There are over 3,000 known minerals. Some of the most common ones and their uses are: Asbestos has an unsavory reputation for causing cancer in people who work around it. It is a fibrous mineral with incredible fire retarding properties. Quartz (silica) is the most abundant mineral on earth. It is the name for a large family of rocks including the jaspers, agates, onyxes, and flints. Quartz is used in concrete, glass, scientific instruments, and watches. Most importantly today, it is used to make silicon semiconductors. Silica is used in desiccants to remove moisture from the air. It is also used in sandpaper and glass making.

  • Ingredients: The term "ingredients" is commonly used in the context of food labels. The food label provides information such as what the food is, manufacturers details, nutrition information, ingredients, weights, and more. When reading the ingredient list, it is important to look for foods that contain saturated fat, added salt, added sugars, and alcohol, as these should be limited in our diet according to the Australian Dietary Guidelines.

I did not find any information related to the positive or negative aspects of rocks or their ingredients and materials.
