Rocks can melt when they become hot, which can lead to pieces breaking off.

Rocks become ice when they get cold, which can later melt and wash away.

Rocks move faster when they are heated, which can cause the pieces to eventually move away.

The correct answer is: "Rocks expand and contract when they are heated and cooled, which can cause them to break."
Explanation: Temperature changes can have a significant impact on the weathering of rocks. When rocks are exposed to heat, they expand, and when they are exposed to cold, they contract. This repetitive expansion and contraction can put stress on the rock, leading to the formation of cracks and fractures. Over time, these cracks can widen and deepen, causing the rock to break apart. This process is known as thermal stress weathering. So, the expanding and contracting of rocks due to temperature changes is what ultimately leads to their weathering.
