How are federal and state powers constitutionally delineated describe?

Modern democracies divide governmental power in two general ways; some, like the United States, use a combination of both structures. The first and more common mechanism shares power among three branches of government—the legislature, the executive, and the judiciary. The second, federalism, apportions power between two levels of government: national and subnational. In the United States, the term federal government refers to the government at the national level, while the term states means governments at the subnational level.

Constitutional powers and responsibilities are divided between the U.S. federal and state governments. The two levels of government also share concurrent powers
