D)Temperature has no effect on rock weathering.

Question

Quizplus · Accepted Answer

In deserts, warm temperatures and low soil moisture contents allow for some mechanical weathering. Chemical weathering requires moisture, which is lacking in desert environments. This means that rocks in deserts are more likely to break apart through physical processes such as wind erosion and thermal expansion and contraction, rather than chemical breakdown. Therefore, there is less material available for the formation of thick deposits of soil.
