Dirt is generally considered heterogeneous because it consists of a mixture of various particles, such as minerals, organic matter, water, and air, that can be distinctly identified. The composition can vary widely from one location to another and even within a single sample. This variability in texture, color, and particle size makes dirt a classic example of a heterogeneous mixture.
