Final answer:
The full faith and credit clause and state extradition are examples of horizontal federalism, which involves interactions among states, such as recognizing other states' legal decisions and ensuring extradition.
Step-by-step explanation:
The full faith and credit clause and state extradition as outlined in Article IV, Sec. 2 of the U.S. Constitution are examples of e. horizontal federalism. Horizontal federalism refers to the various types of interactions that occur among states in the United States. This includes the full faith and credit clause found in Article IV, Section 1, which requires states to accept court decisions, public acts, and contracts of other states, as well as facilitating extradition between states to ensure that justice is served when someone flees a state to avoid punishment.
In contrast, dual federalism, also known as 'layer-cake federalism', involves a clear delineation of authority and programs among the levels of government—federal and state.
