Answer:
a. True
Step-by-step explanation:
Weathering is the process of transformation of rocks by disintegration (physical) or decomposition (chemical) of their structures, giving rise to sediments and interfering with sedimentary processes such as erosion, diagenesis and pedogenesis (soil formation).
Rocks appearing on the surface become exposed to external or exogenous relief transforming agents such as water and wind force. As a result, they disintegrate in oxidation or “washing” processes of their covers, and remain exposed to temperature variations. All of these effects are considered weather events.
