Final answer:
Weathering is the process of disintegrating and decomposing solid rock into small fragments through physical and chemical factors.
Step-by-step explanation:
The disintegration and decomposition of solid rock into small fragments is called weathering. Weathering is a natural process that occurs due to physical and chemical factors.
Physical weathering involves the breakdown of rock through mechanical forces, such as temperature changes, ice wedging, and abrasion. Chemical weathering involves the alteration of rock compositions through processes like oxidation, hydration, and carbonation.
