The concept of external and internal processes was introduced at the beginning of the chapter. In the accompanying photo, external processes are clearly active. Describe the role mass wasting is playing. Identify one feature that is the result of mass wasting.

Earth Science 13
Describe at least one situation in which an internal process might cause or contribute to a mass- wasting process.

Earth Science 13
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 it
