 - 1. Rocks and Minerals are natural solid substances that make up the earth's crust. They are composed of various chemical elements and occur in a wide range of shapes, sizes, and colors. Rocks are made up of one or more minerals and are classified based on their formation process. Some common types of rocks include igneous, sedimentary, and metamorphic rocks. Minerals are naturally occurring inorganic substances with a specific chemical composition and atomic structure. They have various physical properties like color, hardness, and luster. Both rocks and minerals play a crucial role in geology, industry, and everyday life.
