Physical weathering is defined as **the breaking of rock into smaller pieces from nonchemical processes**. This process can occur through various mechanisms such as freeze-thaw cycles, thermal expansion, abrasion from wind or water, and biological activities. Unlike chemical weathering, physical weathering does not change the chemical composition of the rock; it only reduces its size and alters its physical structure.
