About this app
The "Minerals in Rocks" application describes various minerals, their properties, and their formation. This app categorizes and sketches the differences between minerals and rocks, using a few examples to describe their formation. This app is educational and can be used as a reference for important properties such as a mineral’s Hardness, Cleavage, Fracture, Crystal form, and Fluorescence. This app also has an option to stop and play the audio. There is also a quiz section with a set of questions to review one’s knowledge on minerals.
