Your answer is correct. A canyon is indeed described as a deep valley with steep sides that has been formed predominantly by the erosive action of rivers over a significant amount of time. The process of erosion removes soil and rock, deepening the valley and creating the iconic steep walls that characterize canyons. This natural phenomenon is commonly found in various geographical locations around the world and is well-known for its stunning landscapes and unique ecosystems.

The other terms do not relate to the geographical feature described. "Professional" might pertain to careers or occupations, "All-Inclusive" refers to a type of travel package that covers all expenses, and "Time Log" typically relates to recording periods of time or activities. None of these options capture the essence of a deep valley shaped by river erosion.
