What describes clods in soil composition?

Clods in soil composition refer to chunks of soil that are formed due to various natural processes, primarily through the action of moisture and mechanical forces. These chunks can happen when the soil dries out, causing it to break apart into irregular shapes. This process is often a result of soil texture and structure interacting with environmental factors, such as freeze-thaw cycles or the activity of soil organisms that can compact or break up the soil.

While some clods may appear similar to artificially created soil aggregates, they are typically a natural phenomenon reflecting the soil's condition. The correct answer highlights the casual nature of clod formation, aligning with soil's natural tendencies rather than emphasizing an artificial mechanism. Thus, understanding clods as a natural occurrence underscores the dynamic nature of soil and the environmental processes that shape its structure over time.
