Soil Profile Diagram: Layers, Root Systems, and Groundwater Flow #3048626 (License: Personal Use)

This black-and-white scientific diagram depicts a vertical soil剖面 with distinct horizons: an organic-rich A-horizon covered in vegetation, a B-horizon with accumulated minerals, and a C-horizon overlying bedrock. Water percolates through porous soil layers, converging toward a labeled water table ('m'), while plant roots extend downward, interacting with moisture and nutrients. The illustration emphasizes hydrological and biological processes within terrestrial ecosystems.

Used in geology, environmental science, and agriculture educational materials to explain soil formation, infiltration, and aquifer recharge; matches user intent for learning or teaching earth system processes.
