Rocks vs. Minerals: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 24, 2023
Rocks are composed of multiple minerals or mineral fragments, while minerals are naturally occurring inorganic substances with specific chemical compositions.
Key Differences
Rocks and minerals differ primarily in composition: while rocks comprise various minerals, minerals possess a singular, defined chemical composition.

By nature, minerals are inorganic, crystalline substances. On the other hand, rocks are aggregates, formed by a collection of one or more minerals.

Mineral properties such as luster, hardness, and streak are used by geologists to identify them. Rocks, however, are classified based on their formation process, composition, and texture.

When considering formation, rocks usually undergo multiple stages and processes like cooling, compaction, and cementation. Minerals, conversely, crystallize from solutions or form as a result of high temperature and pressure changes.
