Rock cycle processes exchange energy and materials with the atmosphere, the hydrosphere, and the biosphere. 2. Describe ways in which rock cycle processes exchange energy and materials with the atmosphere, the hydrosphere, and the biosphere. a. Rain and air aided by acids and other chemicals secreted by plants, decompose solid rocks to form large amounts of clay and other sediment.
