The correct response is: Rocks expand and contract when they are heated and cooled which cause them to break.
The correct answer is:
Rocks expand and contract when they are heated and cooled which cause them to break.
Explanation: Temperature changes can lead to weathering of rocks because rocks expand when they are heated and contract when they are cooled. This continuous expansion and contraction can cause stress on the rock, leading to the formation of cracks and eventually causing the rock to break apart. This process is known as thermal weathering.
