which climate favors mechanical weathering?\no dry climate\no cold climate\no warm climate\no desert climate

Brief Explanations:

Mechanical weathering is enhanced in cold - climates. In cold regions, water can seep into cracks in rocks. When the temperature drops below freezing, the water freezes and expands, exerting pressure on the rock and causing it to break apart. This process, called frost - wedging, is a common form of mechanical weathering. Dry and desert climates have less water for such processes, and warm climates may have more chemical weathering due to higher temperatures and more active chemical reactions.

Answer:

B. cold climate
