Earth is a dynamic planet whose surface is shaped by active physical agents of change. Two broad systems—endogenic and exogenic—organize these agents in Part III.
The endogenic system (Chapters 12 and 13) encompasses internal processes that pro- duce flows of heat and material from deep below Earth’s crust. Radioactive decay is the principal source of power for these processes.
