What do geologists observe and measure from soil?

Geologists observe and measure various properties of soil, including its texture, structure, and composition, to understand its formation and behavior. They analyze mineral content, organic matter, moisture levels, and pH to assess soil fertility and stability. Additionally, geologists study soil layering, or horizons, to interpret geological history and assess potential hazards, such as erosion or landslides. These observations help inform land use, agriculture, and environmental management.
