Which soil property is most influenced by particle size and affects water movement?

• A. Soil Particle Size
• B. PH Level
• C. Elevation
• D. Mineral Content

Answer: (A)

Particle size shapes soil texture, which dictates the size and arrangement of the spaces between particles. Those pore spaces control how water moves: soils with larger particles (like sand) have bigger pores, so water drains quickly and moves through easily, but they don’t hold much water. Soils with smaller particles (like clay) have many tiny pores, which hold more water but move it slowly. Because the ability of water to infiltrate and drain is tightly bound to the particle size that sets texture, this property is the one most influenced by particle size. pH level relates to acidity and is more about chemical conditions than pore structure, elevation is a landscape factor, and mineral content affects chemistry and nutrients rather than the physical flow of water through the soil.
