**a)** **Source of building materials**: Rocks like granite, limestone, and ballast are crucial for construction of roads, buildings, and other infrastructure.  
**b)** **Source of minerals**: Rocks contain valuable minerals such as fluorspar, soda ash, and various gemstones, which are extracted for industrial use and export.

**a)** **Field observation**: Directly examining rock outcrops, noting their color, texture, hardness, layering, and any associated features like faults or folds.  
**b)** **Sampling**: Collecting small pieces of different rock types for closer examination or laboratory analysis to determine their mineral composition and origin.
