Question

Quizplus · Accepted Answer

The small size of sand particles is a result of physical weathering, which involves the breakdown of larger rocks and minerals into smaller pieces due to weathering agents such as wind, water, and temperature changes. This process can occur naturally over time without artificial grinding or the influence of animals. Heat and pressure are more commonly associated with the formation of metamorphic rocks, rather than the breakdown of sand particles.
