Building Blocks of Rocks:
The building blocks of rocks are the components that make up their composition. These building blocks include:
1. Minerals:
- Minerals are naturally occurring inorganic substances that make up the majority of rocks.
- They have a specific chemical composition and crystal structure.
- Examples of minerals include quartz, feldspar, mica, and calcite.
2. Sand particles:
- Sand particles are small, granular materials that are often composed of minerals like quartz.
- They are a common building block of sedimentary rocks, such as sandstone.
3. Pebbles:
- Pebbles are larger than sand particles and are often composed of different types of rocks or minerals.
- They can be a building block in conglomerate or breccia rocks.
4. Stones:
- Stones are larger and more solid than pebbles, usually measuring more than 10 centimeters in diameter.
- They can be made of various types of rocks, such as granite, basalt, or limestone.
Therefore, the correct answer is option B: Minerals. Minerals are the primary building blocks of rocks, while sand particles, pebbles, and stones can also contribute to the composition of certain rock types.
