Question

which climate favors mechanical weathering? dry climate cold climate warm climate desert climate

Explanation:

Mechanical weathering involves physical breakdown of rocks. Cold climates have freeze - thaw cycles (water seeps into rocks, freezes (expands), thaws, repeats). This expansion and contraction due to freezing and thawing is a major mechanical weathering process. Dry and desert climates (which are often dry) have less water for such freeze - thaw (if cold is not present). Warm climates may have more chemical weathering (due to more water and higher temperatures facilitating chemical reactions) rather than mechanical.
