Mass wasting is influenced by many processes associated

(choose chapter or problem)

Mass wasting is influenced by many processes associated with all four spheres of the Earth system. Select three items from the list below. For each, outline a series of events that relate the item to various spheres and to a mass-wasting process. Here is an example that assumes frost wedging is an item on the list: Frost wedging involves rock (geosphere) being broken when water (hydrosphere) freezes. Freezethaw cycles (atmosphere) promote frost wedging. When frost wedging loosens a rock on a cliff, the fragment tumbles to the base of the cliff. This event, called a rockfall, is an example of mass wasting. Now you give it a try. Use your imagination. a. Wildfire b. Spring thaw/melting snow c. Highway road cut d. Crashing waves e. Cavern formation (see Figures 5.42 and 5.43)
