Question

what is the weathering process that occurs when rocks expand in the heat of the day and contract during the cool night-time​

Answer 1

Answer:

Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens. Over time, it crumbles.
