Weathering Process. The weathering process occurs when rocks are exposed to the hydrosphere (water) and atmosphere (air).  These agents can change the physical and chemical characteristics of rocks.  As rocks are broken down (weathered), they can be classified as different types of sediments, which are: o boulders, cobbles, pebbles, sand, silt, clay, and colloids. See page 6 of the Earth Science Reference Tables explains the sizes of each of these sediments.
