How are rocks important to us?

Solution
Rocks are very important to us because they provide useful materials like minerals, metals, and fuels such as coal and petroleum. They are used in building houses, roads, and monuments. Over time, rocks break down to form soil that supports plant growth. Some rocks also store groundwater, which we use for drinking and irrigation. Thus, rocks are essential for our daily life and for the environment.
