The best example of physical weathering is a) the cracking of rock caused by the freezing and thawing of water. This process, known as freeze-thaw weathering, occurs when water enters cracks in rocks, freezes and expands, causing the rock to crack further. The other options pertain to sediment transport, chemical weathering, or deposition rather than physical weathering.
