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.

Answer 5

when they are heated and contract when they cool down. This repeated expansion and contraction can lead to the weathering of rocks. As rocks heat up, they expand, creating stress within the rock structure. When the rock cools down, it contracts, which can result in the creation of cracks and fractures. Over time, these cracks and fractures can become larger due to the continuous expansion and contraction, eventually causing the rock to break apart into smaller pieces. This process is known as thermal weathering and is mainly driven by temperature changes.

Answer 6

when they are heated and contract when they cool down. This continuous expansion and contraction due to temperature changes can lead to weathering of rocks. When rocks are heated, they expand and become more fragile. As they cool down, they contract, causing stress and potential fractures within the rock. Over time, these repeated cycles of expansion and contraction can weaken the structure of the rocks, leading to the formation of cracks and breaking off of pieces. This process, known as thermal weathering, is particularly noticeable in regions with large temperature variations, such as deserts or mountainous areas.
