Answer:
Weathering
Step-by-step explanation:
Weathering is the process by which large pieces of rock are broken down by natural processes into smaller pieces. Eventually, through the many types of weather and then compacting, soil is formed. Weathering is divided into two general categories: physical weathering and chemical weathering. An example of physical weathering is thermal stress (expansion and contraction due to heating by the Sun), while an example of chemical weathering would be the breakdown of rocks by acids such as carbon dioxide.
