Question

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

Explanation:

Mechanical weathering, like frost wedging (water freezing in rock cracks, expanding to break rock), is driven by repeated freeze-thaw cycles. Cold climates experience frequent temperature fluctuations around the freezing point of water, which accelerates this process. Dry/desert climates have less water for freeze-thaw, and warm climates favor chemical weathering more.

Answer:

cold climate
