Quizplus · Accepted Answer

Layer-cake federalism, also known as dual federalism, was characterized by a clear distinction between state and federal government authority. Each layer of government had well-defined responsibilities, and there was little overlap of authority between the two. In contrast, marble-cake federalism, also known as cooperative federalism, is characterized by the intertwined authorities of state and federal governments. The two layers of government work collaboratively to address policy issues, and there is significant overlap of authority between the two.
