The correct answer is - C. moisture is lacking and organic acids are scarce.
The deserts are not a place where the chemical weathering is something that can influence the erosion processes and change the landscape. This is because the moisture and organic acids are very scarce in this environment. The lack of moisture and organic acids is due to the very small amount of precipitation, which it can not appear not just for months, but for years, or even decades. That makes the deserts very dry, and the weathering type that is the dominant in them is the mechanical weathering caused by the winds.
I think the correct answer among the choices presented above is option C. In the desert environment, the chemical weathering of rocks is generally reduced because <span>moisture is lacking and organic acids are scarce which are the cause of chemical weathering. </span>
