    Question: Which fruit is commonly known as "Fruit of New World"? (IFFCO 2022)

    Options:

    Plasticity
    Adhesion and cohesion
    Flocculation
    All of the above

    ✅Explanation:

    • Soil colloids are tiny particles with a large surface area and carry electrical charges. These characteristics give them unique properties that greatly influence soil behavior:
    Plasticity: Soil's ability to change shape under pressure and retain that shape when the pressure is removed. Clayey soils, rich in colloids, exhibit high plasticity.
    Adhesion and Cohesion: Adhesion is the attraction of soil colloids to other surfaces, while cohesion is the attraction between soil colloids themselves.
    Flocculation: The clumping of dispersed soil colloids due to changes in electrical charges.
