As soils age the soil typically becomes __________.

(2 answers are correct)

BlackTom AI · Accepted Answer

When considering how soils evolve as they age, several patterns are commonly discussed in pedology. 
Option 1: more clay rich. As soils weather over time, clay particles can accumulate in the soil profile due to illuviation and mineral transformations, leading to a relatively higher clay content in certain horizons. This makes sense as a general trend in many mature soils. 
Option 2: redder. Aging soils often exhibit stronger iron oxide development and leaching patterns that intensify red or yellow hues, particularly in the A and B horizons, so a redder color with age is plausible. 
Option 3: soil profile do not change over time. This is a mischaracterization; soil profiles typically evolve with time due to weathering, organic accumulation, horizons forming, and leaching, so saying the profile does not change contradicts widely observed soil development processes. 
Option 4: soil profile becomes thinner. In reality, soil profiles can become deeper or at least more distinct in their horizons as weathering and biological activity accumulate vertically; stating that the profile becomes thinner oversimplifies and often conflicts with how horizons deepen or differentiate over time. 
Option 5: less clay rich. This would oppose the common aging trend described above, since many aged soils show stable or increased clay accumulation in some horizons rather than a decrease in clay content. 
In summary, the two statements that align with typical soil aging processes are that soils become more clay rich and tend to become redder due to iron oxide development, while the other options misrepresent how soil profiles change with time.
