2. Agriculture: Rocks such as limestone and phosphate are used as fertilizers in agriculture to provide essential nutrients to crops.

3. Energy: Fossil fuels, such as coal, oil, and natural gas, are formed from the remains of plants and animals that lived millions of years ago and were buried and compressed by sedimentary rocks.

4. Jewelry: Precious and semi-precious stones, such as diamonds and emeralds, are used in jewelry.

5. Technology: Rocks and minerals are used in the manufacturing of electronics, such as smartphones, computers, and TVs. For example, quartz is used in electronic devices as a timing device.

6. Science: Rocks provide valuable information about the Earth’s history, including the processes that formed them and the environments in which they were formed.
